So how do I estimate the number of active users? Bozhemoi! I decided I'd do a survey of the r-help list.

[R] Cran package directory 404 error since 30th December
I have been getting a object not found error trying to access the CRAN package directory since the 30th December. I have tried several mirrors with the same error. A search here only shows a single question on this from anyone else (on the 30th December) which wasn't answered. I am surprised that there hasn't been more comment on this. Is there an announcement somewhere about this that I have missed, that say CRAN packages is down for maintenance or some other planned down time.

Re: [R] Cran package directory 404 error since 30th December
Thanks Brian, The short answer is that this needs someone in Vienna to fix (people do have vacations and take weekends off), and that the web/packages directory is pure sugar: the packages are still there, the check results are there ... just the summary pages are missing and they are accessible via one (at least) of the mirrors. The person whose message here was unanswered bombarded many people, including CRAN and me personally, so did get several replies. I'm not subscribed to R-devel, and usually just sit and wait for these things to sort themselves out. Generally, even during holiday periods this sort of thing get sorted amazingly quickly, but I was puzzled by the lack of comment. suggesting it may be some DNS look up error at my end. It came to light when browsing he task views and then wanting to read the manual for a particular package, but getting a 404 when I clicked the link. I was obviously un lucky with the mirrors I tried. Any thanks again.

Re: [R] Can we prepare a questionaire in R
1) Is there a way to populate html form element values directly into R or is it only possible to get the values into a db or an excel file or a csv file and import it for data analysis. I realise this isn't exactly what you are asking, but it is a possible solution. If you google or search these forums you will find information on linking R to the spreadsheet in Google Docs. With GoogleDocs you can create forms that can be filled in online or via email, which automatically populate a google spreadsheet. Running the R code for the analysis then automatically updates with the latest data from the spreadsheet. So the analysis is always based on the latest data. Not sure if that helps, but it may be worth exploring.

Re: [R] medians in Wilcoxon disagree with median function
David, I am sure I am opening myself up to looking stupid, Or exposing a failure to read the help page. Well no, and of course I did read the help pages as well as several introductions on Wilcoxon before posting, but as I said in my other post it is generally not at all clear, the distinction between difference between medians and median differences. I didn't find the help page all that enlightening, given that I came to them with a firm misconception about medians and the dummy data sets I created to try and work out what might be going on, plus data sets I pulled from Wilcoxon tutorials gave differences in medians that matched the Wilcoxon median differences. Now that I realise that the Wilcoxon gives median differences, and how they are calculated, it all makes more sense. I realise the data are highly skewed, but what started out as a quick look to see what a Wilcoxon looked like with this data, became an all morning search through text books and google, together with experiments in R, to try and work out why I was getting this discrepancy in locations. I now know why.

Re: [R] Cost-benefit/value for money analysis
Ben Perhaps you can specify your question more precisely, or differently. The way I interpret it, if there are no interactions in price (e.g. you get a discount for buying more than one book at a time) or in value (e.g. you learn more from one book having read another), then you get the best value/price ratio by taking only the book with the highest value/price. (If you take no books at all, your value/price ratio is undefined.) The algebra below shows that combining a lower value/price book with a higher one always lowers your overall value/price ratio. Thanks, for the pointers on R functions. My question was as superficial as it sounded. I have a commercial programme that does this (one of several that are available), and wondered if there was an R package that provided the same tools. It's a common tool, and I had hoped to have explained enough to allow an appropriate package to be identified, so I could have a quick look at what it does. But having started this, I now feel obliged to clarify the question. I only chose books as an easy example, you could substitute alternative marketing strategies, monitoring programmes, choice of ornaments for a new house, or holidays etc. So there could be only a few potential combinations or hundreds. But to stick with the books, and only three options: A, B and C Book A costs $100 and I have given it a subjective value of 50 Book B costs $36 and I have given it a subjective value of 60 Book C costs $50 and I have given it a subjective value of 80 So book A is costing me $2 per value unit, Book B $0.6 per value unit and book C £0.63 per value unit. Buying books A+B gives me a $1.24 per value unit Buying books A+C gives $1.07 per value unit Buying books B+C gives 0.61 per value unit Buying books A+B+C gives 0.97 per value unit So in terms of value for money, there are three contenders Book B on its own, Book C on its own, or buying both books B and C. Book B $36.00 and value 60 Book C $50.00 and value 80 Book B+C at $76.00 and value 140 Depending on how you are using this tool, you can either use it to decide how spend an existing budget, or use it to set a budget. Seems hardly worth the bother for three books but if you are looking at 20 books or 30 different monitoring options etc, it gives a useful insight into how best to spend or set a budget The commercial software graphs this costs vs values so you usually end up with some sort of an asymptotic graph where you can see that spending below a certain budget gives a very poor return.

Re: [R] Cost-benefit/value for money analysis
David, I think a similar argument at the margins would show that even if the task were specified as maximal value with a budget, simply ordering by the value/price and buying until the cumsum of the price was greater than budget would solve the alternate statement of the problem. I suppose there might be situations where there were marginal choices of buying two books whose value/price was less than marginally maximal because two other marginally maximal choices would break the budget. This sounds like a homework problem and I don't see any student effort yet. Search terms include: decision analysis , cost-benefit analysis, or utility theory. Hopefully, my response to Ben will clarify my question, and why I am asking it. At the moment (and that may change) I'm not specifically interested in how you do it R, just as to whether there is a package aimed at this kind of Cost Benefit analysis.

Re: [R] Cost-benefit/value for money analysis
Denis, Are you perhaps thinking of conjoint analysis? Thanks, but as far as I can make out, having just looked at conjoint analysis, it looks like some form of discriminant analysis, which is not what I am looking for. I only have two variables cost and value. I am ignoring how you establish the value, I just need to be able to assess every possible combination of costs and value. Its common technique in the Decision Analysis literature (and specialist Decision Analysis software), but I have never seen it given a Specific name. But of course it may have several names, and be used across different disciplines for different purposes. Its such a common tool, that I was hoping that someone would instantly recognise, what I was describing, and be able to say that it was available in a particular package. But I had never looked at conjoint analysis before, so nice to know it exists.

[R] Cost-benefit/value for money analysis
I assume this has a proper name, but I don't know what it is and wondered if anyone knew of a package that might do the following, or something similar. As an example, assume I have borrowed and read 10 books on R , and I have subjectively given each of them a value score in terms of how useful I think they are. I also know how much each costs in terms of money. What I would like to do is to calculate the costs of every possible combination of the 10 books, and plot the total monetary value for each of these possible combination with their associated subjective value totals, to help decide which combination of books represents the best value for money. I know that some specialist decision analysis software does this sort of thing, but was hoping R might have an appropriate package.

Re: [R] R reports
Good grief. Adding a report function is not going to make R less flexible. Don't you want to use a tool that's relevant to the rest of the world? That world is much bigger then your world. This is ridiculous. How big a world do you want , Google use R successfully , and it is being used by NIST to analyse what is happening with the oil disaster in the Gulf of Mexico. As an environmental consultant I use R in preference to other programs I have available (Stata, Statistica and Genstat), partly because of its flexibility, but a lot because , in conjunction with SWeave, (which I normally use via Lyx or Orgmode in Emacs) it allows me to produce clent ready reports. Something I couldn't do with the reporting facilities with the other programs. Although, it has and is, taking a lot of learning I am producing client ready reports faster and of a higher quality than I was before. Working to tight budgets and tight deadlines this is important. It has certainly been a lot of hard work to learn, and I am still far from being where I would like to be. And like you, I moaned about how easy things were in the other programs, but until you have experienced the full power of R,and yes, the flexibility it gives, you really are commenting from a platform of ignorance. I would listen carefully to people like Frank Harrell, who has a lot of experience of SAS and R, as well as a lot of experience of working in the very real world of medical research. I would also strongly encourage you to take R for what it is, and learn the many different ways of producing reports. It is a lot to learn, but in my mind well worth it.

author = {{R Development Core Team}},

address = {Vienna, Austria},

}
But the author formatting in the Jabref preview and when I paste it
into Lyx is parsed to Team, R. D. C.
As far as I can make out from the help, the double curly brackets
should stop this parsing.
Googling has drawn a blank, so does anyone know how I can get this to
format as R Development Core Team rather than Team, R.D.C.

[R] resampling problem counting number of means above a specific value
I am trying to modify some code from Good 2005.
I am trying to resample the mean of 8 values and then count how many
times the resampled mean is greater than 10. But my count of means
above 10 is coming out as zero, which I know isn't correct.
I would appreciate it if someone could look at the code below and tell
me what I am doing wrong.
Many thanks,
Graham

Re: [R] resampling problem counting number of means above a specific value
David,
Thanks, its me getting mixed up I actually meant less than or equal to
10. That apart, I guess the code is OK, I just expected, especially
as I increased N that I might have got some means less than 10, but
having gone back to it , I see I need a million iterations before
getting two means less than 10.
It seems I misjudged the probabilities.
Thanks again.
Graham

If that is your goal, then why are you using = and not in your test?

Re: [R] Sweave recode(car) and Lyx, compiling but not executing on Mac
Just to follow this up. Changing the document encoding in Lyx from the default (whatever that was) to utf8 (with some help from Jay) allowed some samplerecode code to run (it wouldn't run initially), but my original code still won't run. Strangely looking at the Latex code window in Lyx shows some strange syntax highlighting in my code cabbages$Year-recode(cabbages$Year,'X2001'... The code is higlighted between the $ signs and I wonder if this suggests there are still some sort of encoding problem.

Re: [R] Sweave recode(car) and Lyx, compiling but not executing on Mac
While this is a bit embarrassing , it seems I had two problems, one was that the recode command seems to need utf8 coding rather than the Lyx default (which is fine), plus I had typing error in the data set, which is not fine :-(. I rewrote my code using the with command which allowed it to run, but it then became obvious that the recoded resuts were not what I had expected. The typing error then being obvious. The first entry in my rcode was 'X2001'='2001' but the first level in the data set was X20001 and this was enough to cause recode to fail in my original code, but run using the with command. Its now working. Thanks to everyone for there help. Graham 2009/6/12 Graham Smith myotis...@gmail.com: I am just beginning to use Sweave with Lyx on a Mac (R2.8.1).

Re: [R] Simple Gantt like chart for numbers rather dates
Jim, Gabor is right, gantt.chart comes close but you will have to change all the POSIXct axis calls to plain old axis calls and manually create the list of gantt.info with the x values as numbers.

Re: [R] Simple Gantt like chart for numbers rather dates
Gabor, Then try something like this.

Re: [R] ubuntu repository for R
Dirk,
Thanks for this, in fact I did notice the error after posting. I didn't
know there was an r-sig-debian list, I shall join and use it for any future
questions of this type.

Marielle,
Thanks for this. I think I have done as you suggest but still get the
public
key error. Do I need to reboot to get it to work: here is the script:

Usage: apt-key [command] [arguments]
Manage apt's list of trusted keys
apt-key add file - add the key contained in file ('-' for
stdin)
apt-key del keyid - remove the key keyid
apt-key export keyid - output the key keyid
apt-key exportall - output all trusted keys
apt-key update - update keys using the keyring package
apt-key net-update - update keys using the network
apt-key list- list keys
Notice that Marielle (correctly) wrote
gpg --export --armor E2A11821 | sudo apt-key add -
whereas you used
gpg --export --armor E2A11821 | sudo apt-key add-
and the space matters. You tell apt-get to use a command 'add-' which
doesn't exist whereas you need to tell it to use 'add' with '-' as
input (meaning the key will be read on stdin).
In the future, consider the r-sig-debian list for Debian / Ubuntu
questions. We are now fairly off-topic for R.

I am trying to get synaptic to work with R
I have added http://cran.uk.r-project.org/bin/linux/ubuntu as the
URL
and
hardy/ as the distribution.
Try a different mirror, I used http://cran-mirror.cs.uu.nl/. When you
try
apt-get update, you'll get a warning (that's better than an error ;)

Re: [R] Editor for Mac OSX
Have a look at TextMate http://macromates.com/ Graham 2008/6/18 Sebastian Leuzinger [EMAIL PROTECTED]: Dear R-list I am (forced) to change from Linux to Mac and am now looking for a new editor for R. I would like one that features a split window (console + editor) as well as syntax highlighting. Can anyone help? Especially the split-window feature does not seem to be easily available in the editors desribed on the R-help site, except Emacs, which I am reluctant to start using.

[R] extracting averages from smooth.ppp output on spatstat
I have used smooth.ppp in spatstat to create a smoothed surface plot based on randomly selected depths across a lake (as marks). I wonder if based on the smoothed surface plot if I can calculate the average depth for each 10x10 grid square across the lake. I can't see any obvious way of doing this and would appreciate some pointers.

Re: [R] R2HTML package and Open Office: text only pasted
Max, Thanks, a few people have suggested this offlist and I am having a look at this, but I just trying to quickly get results into a word processor in a more easily read format than a straight copy and paste. Open Office Writer was ideal in the past, because a straight paste produced a formatted table, something must have changed in the more recent version but so far no reply from the Open Offfice help list. However, now that I have grasped how ODFWeave works I can certainly see that being useful for more formal document creation.

Trying paste special only gives an option to paste unformatted text. Equally, with Writer, in the past when I tried this, the results were pasted as a table, but now they are pasted as HTML code. Again trying to use paste special, there is only an unformatted text option. I am using the simplest R2HTML code option, which as a I said, works with Excel HTML2clip(x) I suspect this is more an OOo issue, but hopefully someone has experience of using this combination and can help.
