[R] How are R version types named ? Any convention (like Hurricanes etc)
With reference to R News News: R version 3.0.0 (Masked Marvel) has been released on 2013-04-03. R version 2.15.3 (Security Blanket) has been released on 2013-03-01 R version 2.15.2 (Trick or Treat) R version 2.15.1 (Roasted Marshmallows) ... R version 2.15.0 (Easter Beagle) R version 2.14.0 (Great Pumpkin) Dear R help List, How are these version types named? Masked Marvel comes after Security Blanket comes after Trick or Treat comes after Roasted Marshmallows. Is it some convention like that for Hurricanes in the West. It is totally incomprehensible to me as I am in India.

[R] APIs and R
Dear List, I am compiling a list of R packages that work with social media APIs. Uptil now I have found that 1- Most of these are based on RCurl, XML, rjson 2- Even though the API format is standardized for REST- there seems to be many differences within the APIs, leadinbg to multiple packages that do the required API call - 3- I am specific issues with the following Google +API access through R Linkedin API access through R Twitter +API access through ROAuth and Datasift API (basically a firehose for all social media) within R Again most of the APIs I find have libraries supported by java, ruby,python,curl- but there seems to be some overlooking of R within various API vendors. Has anybody been working with R for social media- I am specifically looking for use cases that avoid rate limiting of free api- and specifically OAuth and APis for LinkedIn, Google + and Datasift using R.

Re: [R] Getting R In Torrents instead of Download Zip Files
Dear Prof D No server side architecture is needed for bit torrents. It runs on peer to peer. You just host one file (torrent file) and your torrent searches for peers (other people having that torrent file/data). To kickstart- you need to host some files on one server, as the mother seed. That also will need just a modification in the search engine list within your local computer 's bit torrent engine(as in add- cran.at in list of sources instead of other sources) You may want to ask Ubuntu /Debian how /why they do it? I may be completely wrong here on the technical code- but I think it does help people from developing world with erratic bandwidth, which is where I come from.

Re: [R] Who uses R with multicore, SNOW or CUDA package for resource intense computing?
R doesnot have a 1 million or two million users (thats an Urban legend thanks to Vance NYT article) . The exact number is not proven and estimated by a variety of association by proxy methods. It could be as low as 5,00,000 or as many as 5 million users. It's like speculating which private equity companies is Goodnight investing in. A better estimate would be counting the number of downloads of R 2.12 or analytical log analysis of various CRAN websites. You can read my 2 cents on using SNOW, DOSNOW, FOREACH on Multi Processor Amazon Instance Here- it is not quite theory but more like a step by step screenshot tutorial- insert your own algol in it to see the ramp up speed. It is an elaboration of the Grossman original opendata post and mashes a bit of code for Tal G (replacing Revo's package for making the connection) http://decisionstats.com/2010/09/27/running-a-r-guiand-parallel-programming-on-amazon-ec2/ or if you like to use Revo's packages or find it difficult to go just commado line - run Ec2 on Windows (and I havent managed the Ubuntu port yet- though EC2 does have REL instances. http://decisionstats.com/2010/10/02/running-r-on-amazon-ec2-windows/ An additional point is Amazon Micro instances are free for a year- for linux but limited to 600~ mb RAM and you probably need to use the small (2 processor instance) to sandbox Websites- http://decisionstats.com http://dudeofdata.com Linkedin- www.linkedin.com/in/ajayohri On Tue, Nov 16, 2010 at 3:09 PM, erik handywu...@gmx.net wrote: Hi, who of you in this forum uses R (http://www.r-project.org/) with the multicore, SNOW or CUDA packages, so for advanced calculations that need more power than a workstation CPU?

I needed to transfer (copy) a workspace file that had been generated in linux (R 2.11) to windows running the same version of R 2.11 (but of course windows binary). Usually, there is no problem in doing this and all objects work as expected. I am often doing this to be able to produce wmf or emf graphic files that I need. This time I had some spectra that I have taken the first derivative of with the sav_gol function in the RTisean package. I know RTisean is just an interface to the Tisean executables. The trouble I am facing is that it seems that the location of the Tisean executables is somehow hard coded to the R workspace file. I assume this since when I try to rerun the sav_gol on the windows machine after copying the workspace file from linux and opening it in windows, RTisean tries to search the Tisean executables from the location that is valid for linux, not windows. RTisean help package says RTisean asks the location of the executables the first time a function is called and that this location is saved in user's home directory for future use. There is no specific information of how this works in windows where there is no obvious home directory. However, I have run R console on windows and it asked this location but I don't know where the information was stored. In linux it is in .RTiseanSettings file in user's home as explained. My questions are: 1) Is there a way I could break the link of the Tisean executables to the linux location so that when run in windows the executables in windows will be used? 2) Is the hard coding of the location of Tisean executables to the workspace image deliberate and necessary?

Beware that this is not a well-defined question: are these physical or virtual cores?, and having them in the system and being allowed to use them are different questions. Package 'multicore' is one that attempts to do this in its function detectCores (see the source code). And on Sparc Solaris it is pretty useless as it gives virtual CPUs, 8x the number of real CPUs.

[R] Running R on Amazon EC2 : Public Snapshot for use
Dear All, I ave created a public snapshot for use on Amazon EC2 using 64 bit Windows. If you want to try R on multiple cores ,remote desktop you can use this snapshot to create copies. It has R, GUIs for beginners (like RCommander , Deducer- Alas rattle failed due to RGtk+) and a lot of R analytical packages. It also has Chrome for browsing, Adobe Reader for reading help, and a dataset WDI (in public downloads folder) for testing sample data. It also has the academic version of Revolution R Enterprise installed on it- so you can see the new XDF format in Revoscaler package for bigger datasets or just play/explore it. The cost of using this would be 3 cents per hour payable to Amazon (micro instance). Detailed instructions on how to use a snapshot or create one of your own are on my website at http://decisionstats.wordpress.com/2010/10/02/running-r-on-amazon-ec2-windows/ It would be interesting to see R visualizations on potentially huge huge datasets using this cloud computing R- if anyone tries it.

Re: [R] News on R s largest corporate partner REVolution Computing and SPSS CEO:
I am sorry. I will refrain from this in the future (using the list which is a technical resource and not a forum inappropriately). My blog has my views on it -http://decisionstats.com so I wont cut and paste on that. I would like to applaud David's team at REvolution for finally releasing an Ubuntu version of REvolution R, though the Windows version 64 bit was developed much earlier. I would like to say that Dave's credentials in open source or his personal technical authority has not been questioned by me ( and I don't think by anyone on this list). The new management is led by an ex Founder of SPSS, so I guess that things are looking up already. A new CEO can only mean more hunger to get R up and running in corporate circles so that smart people who write excellent code start making more money than ...? .

For the past few months we have been working on a B-Round of funding. It was an interesting process and I was happy to be working in my first startup company after so many years in very large corporations. We built a small team to work on Community Engineering, by which we meant developing assets both to benefit the R Language community as well as to entice and inform the Alpha-Geek community to learn and use R. We set up an Advisory Board designed to advise REvolution management about decisions relating to REvo and Open Source, and we helped put REvolution R into the Karmic Koala release of Ubuntu. It was really fun to work in a small, agile team and I felt like I was getting a great education in startups and we were rapidly moving the company forward...Why didn't I join a startup years ago? The funding deal closed on Wednesday last week... Late the next afternoon I received a call from the new COO notifying me that my services would no longer be required at REvolution., effective immediately and with no severance. Apparently, the company is moving in a different direction. http://blog.revolution-computing.com/2009/10/revolution-computing-gets- major-funding-new-ceo.html I was surprised that the new CEO, wasn't personally handling this unpleasant task...but I guess that might have been distasteful after the many assurances he gave me and my team last July at OSCON that we were absolutely critical to the company's success and that he would be making no changes for at least three months after he assumed control. Personal courage in difficult situations is rare. What I find most interesting about today's REvolution announcements is the space they spent thanking the previous management team, given nearly all of us, including the Founders and the Board, were just fired. 47% of the company wiped out and nobody left with more than a year of experience...Shit happens... And so we begin to pick up the pieces and move on. I've spent much of the past few days consoling coworkers, personally breaking the news to the many kind friends who had agreed to help us increase interest in R and Revolution, and working out what I might be doing next. I have some interesting possibilities already, although I'm still open to suggestions...so stay tuned. Meanwhile I can honestly say that the new REvolution Computing will little resemble the company I was proud to join and represent. I still think the R Language is really interesting, but I'm no longer sure REvo is the one to watch in this space anymore...For the sake of my friends among the remaining employees and shareholders I hope I'm wrong.

[R] Putting R Based open source analytics for collobrative spreadsheet working on the Cloud
Dear All, I just posted an interview with Karim Chine of http://www.biocep.net/ who has successfully built a latform for on demand data mining enabled by the cloud through R. Here is an except BIOCEP is built on top of R and Scilab and anything that you can do within those environments is accessible through BIOCEP. Here is what you have uniquely with this new R/Scilab-based e-platform: - *High productivity* via the most advanced cross-platform workbench available *for the R environment*. - *Advanced Graphics: with BIOCEP, a graphic transducer allows the rendering on client side of graphics produced on server s*ide and enables advanced capabilities like zooming/unzooming/scrolling for R graphics. a client side mouse tracker allows to display dynamically information related to the graphics and depending on coordinates. Several virtual R Devices showing different data can be coupled in zooming/scrolling and this helps comparing visually complex graphics. - *Extensibility with plug-ins:* new views (IDE-like views, analytical interfaces...) can be created very easily either programmatically or via drag-and-drop GUI designers. - *Extensibility with server-side extensions: any java code can be packaged and used on server side.* The code can interact seamlessly with R and Scilab or provide generic bridges to other software. For example, I provide an extension that allows you to use openoffice as a universal converter between various files formats on server side. - *Seamless High Performance Computing:* working with an R or Scilab on clusters/grids/clouds becomes as simple as working with them locally. Distributed computing becomes seamless, creating a large number R and Scilab remote engines and using them to solve large scale problems becomes easier than ever. From the R console the user can create logical links to existing R engines or to newly created ones and use those logical links to pilot the remote workers from within his R session. R functions enable using the logical links to import/export variables from the R session to the different workers and vice versa. R commands/scripts can be executed by the R workers synchronously or asynchronously. Many logical R links can be aggregated into one logical cluster variable that can be used to pilot the R workers in a coordinated way. A cluster.apply function allows the usage of the logical cluster to apply a function to a big data structure by slicing it and sending elementary execution commands to the workers. The workers apply the user's function to the slices in parallel. The elementary results are aggregated to compose the final result that becomes available within the R session. - *Collaboration:* your R/scilab server running in the cloud can be accessed simultaneously by you and your collaborators. Everything gets broadcasted including Graphics. A spreadsheet enables to view and edit data collaboratively. Anyone can write plug-ins to take advantage of the collaborative capabilities of the frameworks. If your IP address is public, you can provide a URL to anyone and get him connect to your locally running R. *- Powerful frameworks for Java developers:* BIOCEP provides Frameworks and tools to use R as if it was an Object Oriented Java Toolkit or a Web Toolkit for R-based dynamic application. - *Webservices for C#, Perl, Python users/developers:* Most of the capabilities of BIOCEP including piloting of R/Scilab engines on the cloud for distributed computing or for building scalable analytical web application are accessible from most of the programming languages thanks to the SOAP front-end. - *RESTful API:* simple URLs can perform computing using R/Scilab engines and return the result as an XML or as graphics in any format. This works like google charts and has all the power of R since the graphic is described with an R script provided as a parameter of the URL. The same API can be exposed on demand by the workbench. This allow for example to integrate a Cloud-R with Excel or OpenOffice. The workbench works as a bridge between the cloud and those applications.

[R] SAS CMO and SVP Jim Davis on Open Source, BI , competition, leadership succession others
An interview with Chief Marketing Officer of SAS Institute, Jim Davis. Here is an extract- http://www.decisionstats.com/2009/06/05/interview-jim-davis-sas-institute/ *Ajay -It is rare to find a major software company that has zero involvement with open source movement (or as I call it with peer-reviewed code). Could you name some of SAS Instituteâs contribution to open source? What could be further plans to enhance this position with the global community of scientists?* * Jim -* SAS does support open source and open standards too. Open standards typically guide open source implementations (e.g., the OASIS work is guiding some of the work in Eclipse Cosmos, some of the JCP standards guide the Tomcat implementation, etc.). Some examples of SASâs contributions to open source and open standards include: * Apache Software Foundation* â a senior SAS developer has been a committer on multiple releases of the Apache Tomcat project, and has also acted as Release Coordinator. *Eclipse Foundation* â SAS developers were among the early adopters of Eclipse. One senior SAS developer wrote a tutorial whitepaper on using Eclipse RCP, and was named âTop Ambassadorâ in the 2006 Eclipse Community Awards. Another is a committer on the Eclipse Web Tools project. A third proposed and led Eclipseâs Albireo project. SAS is a participant in the Eclipse Cosmos project, with three RD employees as committers. Finally, SASâ Rich Main served on the board of directors of the Eclipse Foundation from 2003 to 2006, helping write the Eclipse Bylaws, Development Process, Membership Agreement, Intellectual Property Policy and Public License. *Java Community Process *â SAS has been a Java licensee partner since 1997 and has been active in the Java Community Process. SAS has participated in approximately 25 Java Specification Requests spanning both J2SE and J2EE technology. Rich Main of SAS also served on the JCP Executive Committee from 2005 through 2008. *OASIS* â A senior SAS developer serves as secretary of the OASIS Solution Deployment Descriptor (SDD) Technical Committee. In total, six SAS employees serve on this committee. *XML for Analysis* â SAS co-sponsored XML for Analysis standard with Microsoft and Hyperion. *Others *â A small SAS team developed Cobertura, an open source coverage analysis tool for Java. SAS (through our database access team) is one of the top corporate contributors to Firebird, an open source relational database. Another developer contributes to Slide WebDav. Weâve had people work on HtmlUnit (another testing framework) and FreeBSD. In addition, there are dozens if not hundreds of contributed bug reports, fixes/patches from SAS developers using open source software. SAS will continue to expand our work with and contribute to open-source tools and communities. For example, we know a number of our customers use R as well as SAS.

I do not want to fiddle (too much) with building R myself, unless it is real easy and makes a real speed difference. I wish I could ask R to load something exotic like CUDA, but I presume that this is not yet ready for prime-time. PS3 is probably silly, too. in fact, if I am not mistaken (and I may well be), R pre-built does not even take advantage of SSE3 out-of-the-box. software-wise, is there anything unusual that I should heed, or should I just pick of R 2.8.1 from the CRAN archives and be done with it? now, I also have to make some simple hardware decisions.

[R] Interview: Jon Peck on SPSS, R ,Python ...
Dear List, I recently got the chance to interview Jon Peck of SPSS Inc, a pioneering technical statistician working since 1983 (when there were only two substantial statistical software companies as per him ;) (not anymore ;) and currently he is a Principal Software Engineer and Technical Advisor at SPSS. Jon talks of SPSS Inc's involvement with the Open Source, of scripting languages ,Python and a bit of R. The article is also online at my blog and at http://smartdatacollective.com/Home/17206 Regards, Ajay Here is an extract *Ajay- What are SPSSs contribution to Open Source software . What ,if you can disclose are any plans for further increasing that involvement.* *Jon-* I wish I could talk about SPSS future plans, but I cant. However, the company is committed to continuing its efforts in Python and R. By opening up the SPSS technology with these open source technologies, we are able to expand what we and our users can do. At the same time, we can make R more attractive through nicer output and simpler syntax and taking away much of the pain. One of the things I love about this approach is how quickly and easily new things can be produced and distributed this way compared to the traditional development cycle. I wrote about productivity and Python recently on my blog at insideout.spss.com. *Ajay - How happy is the SPSS developer community with Python . Are there any other languages that you are considering in the future.* *Jon-* Many in the SPSS user community were more used to packaged procedures than to programming (except in the area of data transformations). So Python, first, and then R were a shock. But the benefits are so large that we have had an excellent response to both the Python and R technologies. Some have mastered the technology and have been very successful and have made contributions back to the SPSS community. Others are consumers of this technology, especially through our custom dialogs and extension commands that eliminate the need to learn Python or R in order to use programs in these languages.

Re: [R] Inefficiency of SAS Programming
Ok. Basically everything that SAS can do, R can do, but vice versa isnt true. using the Anne package just renames the functions into standardized data and proc steps for user comfort. Once SAS user finds that R is productive , and useful and even more powerful for even less money, he can unload the Anne Package , and move straight away into R like intro of R' It is also a good personal exercise for me to learn how to create R packages.

I think SAS Macros has capability to call R, and execute it without it being in the picture anywhere. So you can use SAS Macros in a file called R.sas In this you can create a macro called %Describe that can call R , load Hmisc ,run the describe function Note you will need repeated use of %put in this %describe for the mapping to take place Use %INCLUDE to include that file in all SAS Programs In fact there is a 50 dollar program written by Phil Rack at www.minequest.com which does exactly that see more here http://www.decisionstats.com/2009/02/interview-phil-rack/ On Tue, Mar 3, 2009 at 8:53 PM, Ajay ohri ohri2...@gmail.com wrote: why didnt you call it procunivariate if that was exactly what you wanted to do .

Re: [R] Inefficiency of SAS Programming
I would like to know if we can create a package in which r functions are
renamed closer to sas language.doing so will help people familiar to SAS to
straight away take to R for their work,thus decreasing the threshold for
acceptance - and then get into deeper understanding later.
since it is a package it would be optional only for people wanting to try
out R from SAS.. Do we have such a package right now..it basically masks R
functions to the equivalent function in another language just for user ease
/beginners
for example
creating function for means
procmeans-function(x,y)
+ {
summary (
subset(x,select=c(x,y))
+
)
creating function for importing csv
procimport -function(x,y)
+ {
read.csv(
textConnection(x),row.names=y,na.strings=
+
)
creating function fo describing data
procunivariate-function(x)+ {
summary(x)
+
)

The PSSASP3.SAS program is a prime example. Look at how you do a vector

regression model. I estimate that using R would easily cut the programming
time of this set of programs by a factor of 4.

Re: [R] Inefficiency of SAS Programming
Immersion therapy can be done at a later stage after the newly
baptized R corporate
user is happy with the fact that he can do most of his legacy code in R
easily now .
I have treading water in the immersion for over a year now.
Most SAS consultants and corporate users are eager to try out R ..but they
are scared of immersion especially in these cut back times ...so this could

masks R functions to the equivalent function in another language just

creating function for means

creating function for importing csv
procimport -function(x,y)

Ajay,
This will generate major confusion among users of all types and be hard
to maintain. A better approach is to get Bob Muenchen's excellent book
and keep it nearby.
Frank
I whole heartedly agree with Frank here. It may be one thing to have a
translation process in place based upon some form of logical mapping
between the two languages (as Bob's book provides). But is another thing
entirely to actually start writing functions that provide wrappers
modeled on SAS based PROCs.
If you do this, then you only serve to obfuscate the fundamental
philosophical and functional differences between the two languages and
doom a new useR to missing all of R's benefits. They will continue to
try to figure out how to use R based upon their SAS intuition rather
than developing a new set of coding and even statistical paradigms.
Having been through the SAS to S/R transition myself, having used SAS
for much of the 90's and now having used R for over 7 years, I can speak
from personal experience and state that the only way to achieve the
requisite proficiency with R is immersion therapy.

Re: [R] Inefficiency of SAS Programming
A further example of software pricing dynamics is the complete lack of awareness of WPS , a UK based software which is basically a base SAS clone with all the features of SAS ( coding read ,write and data read /write) and priced only at 660$ per desktop and 1400$ for server licenses ..very very cheap compared to SAS Base..and it has a Bridge to R for higher level statistics... You would think a corporate user would not have any hesitation to switch to a clone software priced at 10 % ... yet there are hardly any takers for it..in the federal government... :)) people worried about their government's spending should use the new website http://www.recovery.gov/?q=content/contact it is supposed to chronicle this and it would be a good test and control for the Web 2.0 initiatives..

I can confirm pretty much what we already know; it is inefficient. Running on about 1.8 - 2 million cases, it would take just about a whole day to run the entire process from start to finish. That isn't all processing time and includes some time for the analyst to check results between substeps, but I still knew that my day was full when I was working on IQI reports. To be fair though, there are a lot of other factors (beside efficiency considerations) that go into AHRQ's program design. First, there are a lot of changes to that software every year. In some cases it is easier and less error prone to hardcode a few points in the data so that it is blatantly obvious what to change next year should another analyst need to do so. Second, the organizations that use this software often require transparency and may not have high level programmers on staff. Writing code so that it is accessible, editable, and interpretable by intermediate level programmers or analysts is a plus. Third, given that IQI reports are often produced on a yearly basis, there's no real need to sacrifice clarity, etc. for efficiency - you're only doing this process once a year. There are other points that could be made, but the main idea is I don't think it's fair to hold this software up, out of context, as an example of SAS's (or even AHRQs) inefficiencies. I agree that SAS syntax is nowhere near as elegant or as powerful as R from a programming standpoint, that's why after 7 years of using SAS I switched to R. But comparing the two at that level is like a racing a Ferrari and a Bentley to see which is the better car. Dear Anonymous, Nice points. I would just add that it would be better if government-sponsored projects would result in software that could be run without expensive licenses.

Re: [R] Inefficiency of SAS Programming
Sometimes for the sake of simplicity, SAS coding is created like that. One can use the concatenate function and drag and drop in an simple excel sheet for creating elaborate SAS code like the one mentioned and without any time at all. There are multiple ways to do this in SAS , much better and similarly in R There are many areas that SAS programmers would find R a bit not so useful ---example the equivalence of proc logistic for creating a logistic model.

It is now sponsoring the letter 'R.' Last month, I wrote an articlehttp://www.nytimes.com/2009/01/07/technology/business-computing/07program.html about the rising popularity of the R programming language. The open-source software has turned into a favorite piece of technology for statisticians and other people looking to pull insights out of data. On several levels, R represents a threat to SAS, which is the largest seller of commercial statistics software. Students at universities now learn R alongside SAS. In addition, the open-source nature of R allows the software to be tweaked at a pace that is hard for a commercial software maker to match. All told, surging interest in the free R language could affect sales of SAS software, which can sell for thousands of dollars. Rather than running from the threat, SAS appears ready to try to understand R by adopting a more active role in its development. ...Read More at http://bits.blogs.nytimes.com/2009/02/16/sas-warms-to-open-source-one-letter-at-a-time/ [[alternative HTML version deleted]] __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

in R.
The problem is not with criticism of the NY Times article, although
as Pat
Burns and others have pointed out this criticism was somewhat
misdirected
and unrealistic considering the exigencies of newspaper editing. The
problem
was with a number of posts that cast aspersions upon the integrity of
Ihaka and Gentleman. It is these posts that exuded tabloid-esque slimy

I am sure that Ross and Robert would never dream of failing to give
credit
where credit is due and it is almost certainly the case that they
explained
the origins of R in the S language to the writer of the NYT article
(wherefrom
the explanation was cut in the editing process).
Those of us on this list (with the possible exception of one or two

would take it that it goes without saying that R was developed on the

of S --- we all ***know*** that. To impugn the integrity of Ihaka

[R] SAS language to R :interview
Dear List, Please find a frank interview with Phil Rack, creator of Bridge to R ( from both SAS and WPS interfaces). For those unaware of WPS- it is basically a SAS language compiler (read SAS code,writes SAS code,Reads and writes SAS datasets) ,priced at 660 $ a licence ( or estimated 10 times cheaper than Base SAS. The UK based WPC held, WPS doesnt have advanced statistical facilities like SAS /STAT , but that is solved with the Bridge to R . http://www.teamwpc.co.uk/home/ Please find extract of interview- Ajay- How does MineQuest intend to influence the analytical software paradigm? Phil- I think the role for MineQuest in the next few years is twofold. We'll keep offering services to banks and other financial service firms in the area of Operational Risk and SAS programming. The other area is to help these large financial service companies realize that they can save millions of dollars by moving their SAS Server licenses to WPS. This also allows the smaller businesses who have steered away from SAS software because of cost to begin using WPS and not take such a big financial hit. I find it exciting to think how this will also open the job market for the thousands of SAS programmers out there already. The BI battles are taking place on the desktop and Windows Servers and MineQuest has invested a lot of time and effort in creating macro libraries to help these organizations migrate their code to WPS and access R for advanced statistical capabilities. We believe that the bread and butter software for almost any financial organization in the BI realm ultimately revolves around the SAS language for reporting, summarization and disbursement of data and we plan to continue to serve that market.

[R] Deploying a R model on a cloud computer using PMML
Dear List, Please find an interview from Michael Zeller ,CEO, Zementis. Mike talks about how to use an existing model ( created in R) , using PMML as an intermediate for exporting the model, and deploying it on a cloud computer for as low as 1 $ per hour. Regards, Ajay *Ajay-* *What are the traditional rivals to scoring solutions offered by you. How does ADAPA compare to each of them. Case Study- Assume I have 5 leads daily on a Car buying website. How would ADAPA help me in scoring the model ( created say by KXEN or , R or,SAS, or SPSS).What would my approximate cost advantages be if I intend to mail say the top 5 deciles everyday.* *Michael-* Some of the traditional scoring solutions used today are based on SAS, in-database scoring like Oracle, MS SQL Server, or very often even custom code. ADAPA is able to import the models from all tools that support the PMML standard, so any of the above tools, open source or commercial, could serve as an excellent development environment. The key differentiators for ADAPA are simple and focus on cost-effective deployment: 1) Open Standards - PMML SOA: Freedom to select best-of-breed development tools without being locked into a specific vendor; integrate easily with other systems. 2) SaaS-based Cloud Computing: Delivers a quantum leap in cost-effectiveness without compromising on scalability. In your example, I assume that you'd be able to score your 50,000 leads in one hour using one ADAPA engine on Amazon. Therefore, you could choose to either spend US$100,000 or more on hardware, software, maintenance, IT services, etc., write a project proposal, get it approved by management, and be ready to score your model in 6-12 months OR, you could use ADAPA at something around US$1-$2 per day for the scenario above and get started today!

In a move that could have come straight from Mike Judge's Office Spacehttp://en.wikipedia.org/wiki/Office_space, the company has decided to remove the button from their e-mail program of choice, Microsoft Outlook, affecting all 35,000 employees across the globe. In a memo, republished by Foliohttp://www.foliomag.com/2009/nielsen-disable-employees-reply-all-e-mail-functionality, Andrew Cawood, Chief Information Officer for Nielsen Company, writes that the measure will eliminate bureaucracy and inefficiency. I've never been a huge fan of the reply-to-all button either, but removing it sure sounds like a very extreme decision, and claiming that it will eliminate bureaucracy and inefficiency is just plain absurd. Memo below. *REPLY TO ALL FUNCTION TO BE DISABLED* A Message from Andrew Cawood In December, the Nielsen Executive Council (NEC) held an Act Now! event to review suggestions from across the business that would eliminate bureaucracy and inefficiency. Beginning Thursday, January 29, we will implement one of the approved recommendations: removing the Reply to All functionality from Microsoft Outlook. We have noticed that the Reply to All functionality results in unnecessary inbox clutter. Beginning Thursday we will eliminate this function, allowing you to reply only to the sender. Responders who want to copy all can do so by selecting the names or using a distribution list. Eliminating the Reply to All function will: Require us to copy only those who need to be involved in an e-mail conversation Reduce non-essential messages in mailboxes, freeing up our time as well as server space This is one of the many changes being implemented as a result of the NEC Act Now! initiative.
