[R] par(mfrow = ) resets par('cex'), not reduces it
Hello group!
I use R 2.8.0 . I've just found out that par(mfrow =) *resets* par
('cex'), not reduces it as documented. To reproduce:
par(cex = 0.5)
par(mfrow = c(2, 2))
print(par('cex'))
It outputs 0.83, not 0.415 as expected.
Particularly such a behavior makes plot.acf effectively ignore par
('cex') value for multivariate case. I guess there are more situations
where the documented behavior would be more appropriate.
I think it is bug in par implementation not in documentation. Could
anyone comment on this?

[R] specifications windows pc
Hello, I am about to order a new workstation at my university that will be used for R (and other research related tasks). I would appreciate any feedback on the specifications of a very fast machine. The machine should run windows (XP probably better than vista). Which chip, memory size and specification, etc should I be looking for?

I agree. there does not have to be a single human that is exactly as the book descriptions want (and there is *no* single canon in this respect, besides perhaps that a human has one heart and such gross stuff), but there is nothing in the way of there being a human that is accurately described by a particular canonical anatomy. that's why i got shot by your There is no instance of a canonical human body or a canonical heart., which does not make sense to me if it amounts to saying there cannot be. as to A canonical human body will have canonical parts and those canonical parts will have canonical subparts and so on, the problem with the insisted canonicity here is that the more you go into details, the less canonicity to be found. if hardly anyone has more than one heart (and who has none, except for patients under surgery?), hardly any two people will have the same pattern of capillary vessels in a particular location in their body. that is, on the frequentist reading of 'canonicity', the gross level canonical descriptions correspond to strong accuracy of expectations, the more detailed levels correspond to weaker accuracy of expectations. I agree and that is why I shy away from canonical reference in that context. This is why I think it is important to clarify what canonical means. Does it pertain only to a particular level (gross level) or does it entail including all levels of granularity? Is it useful only for theoretical discourse or does it have a place in an ontology that primarily deals with portions of reality? i have read the article on canonicity writen by fabian et al., and besides its logical clarity, i found the definitions completely useless. it might be that i read them too quickly, and had no time to examine them more carefully, but it stroke me that 'canonicity' was defeined there in complete dissociation from the frequentist view. basically, a canonical entity is one that is canonical. Can you direct me to its url, if there is any? I'd be interested in reading it. But let's assume the possibility that 1 or 2 out of 6 billion people fit the idealized, canonical type. I don't see much utility in that. of course. what is useful is that if the canonical anatomy says that there is one heart in a human body, and that it is located here or there, then when a patients comes to me, without additional evidence i assume he/she has one heart and it is here or there. but i have less confidence when it comes to more detailed descriptions; these are more exemplary than canonical. I want a system that can accommodate and provide the information that your heart, my heart and anyone's heart are instances of some type Heart which defines the necessary and sufficient conditions that establish the identity of the heart structure in you, me and everyone else. wait. if you define necessary conditions for an entity to be heart and call this canonical anatomy, then either there are no hearts (because none fulfils the necessary conditions) or there are hearts that instantiate canonical anatomy. i must be wrong, but where. No, I want to stay away from calling it canonical because it will not accommodate as many instantiated hearts as there are or were. This is why I'm re-evaluating my position with regards to any canonical reference to the FMA, unless of course we redefine canonicity to mean some general or generic description. my feeling is that the term 'canonical' is virtually meaningless the way you seem to use it. Not meaningless but rather useless in terms of how it is currently perceived. And again that's why I'm questioning the current use of the term 'canonical'.

Re: [R] readPDF() -- unsure how to install xpdf to make this work?
I never said it *should* work. I was simply trying something out that works on other types of files I've needed in the past (eg: html, csv, dat, etc.). I don't know the details of the pdf format, but I thought it was worth a try, certainly no harm in experimenting, and hence I learned that pdfs aren't stored in the same way that other files i've used in the past are. that's fine, good to learn new things. As for trying the readPDF() function, yes, I have downloaded and used xpdf to convert pdfs into plain text since reading the OP email. However, ow you can make xpdf available to the system so that readPDF () works in R? i don't know, hence why I posted in this thread. You clearly seem to have a solution, fancy sharing?

[R] Using n+1 instances of R to utilise n processors on one machine - something like R with tabbed browsing?
Dear R-help, Please forgive me if any of the following sounds naieve/confused, i've just got back from a mini-pub-crawl, slightly tipsy, and am feeling brave to ask a possibly silly question... also, not to shiny on the technical side of things. Problem - I need to text mine a collection of 10,000 plain text documents, all of which are sitting in a single folder. i don't have any money to buy a database package, and even if i did i have no idea how that would speed things up if i want to do all the processing in R Assumption - It is my understanding that R can only use one processor on a machine when handeling calculations. If you wanted to use 4 processors, than you would have to open up 4 seperate instances of R and share the work between them eg. give each instance of R 25% of the documents you want processed Question - It is possible to have one instance of R to divide the workload, and then that instance opens up 4 other instances of R to do the processing? Or, is sometihng akin to tabbed browsing, where you have one main window and several tabs, each corresponding to a different instance of R? appologies if none of hte above made sense :o) Clair xx O/S: Windows Vista R 2.8.0 __ 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.

[R] Problem loading package created with package.skeleton
Hi,
i'm trying to build an r-package (Windows Vista, R 2.7.2), so i created
one with the package.skeleton() command.
After that i zipped it and tried to load it in R.
Attaching the package via the Windows R-console menu 'Packages/Install
package(s) from local zip-files' failed:
/ utils:::menuInstallLocal()
Error in gzfile(file, r) : cannot open the connection
In addition: Warning messages:
1: In zip.unpack(pkg, tmpDir) : error -1 in extracting from zip file
2: In gzfile(file, r) :
cannot open compressed file 'MeinPacket/DESCRIPTION', probable reason
'No such file or directory'/
The library(package) command failed too:
/ library('MyPackage.zip')
Error in library(MyPackage.zip) :
there is no package called 'MyPackage.zip'/
I checked the current working directory and made sure that the
package-zip was in it, but R couldn't find it anyway.
Does anyone know how to get the package loaded?
Thank you and best regards,
Eli

[R] lapply, sapply
Hello everybody, I have problem with a lapply command, which rather proves that I don't fully understand it. I want to extract from a list that consists of dataframes, the length of the first sequences from a given variable (its part of a simulation exercises). Below is code which does the job, but I think it should be possible to make it more compact. ### Example Data dat -list() dat[[1]] - data.frame(matrix( rbinom(40, 1, .8),nrow=5)) dat[[2]] - data.frame(matrix( rbinom(40, 1, .8),nrow=5)) Code x-sapply(dat,[,3)#Extracting the vector y-lapply(x,rle) #Counting the sequences which is returned as a list z-sapply(y,[, 1) #extracting the first element of the list of sequence counts final-sapply(z,[,1) #extracting the first number, which gives the length of the first sequence, which I want final ### Thanks for your help, Stefan __ 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.

[R] enscript states file for R scripts?
Hi group! GNU enscript is a free (as in freedom) text file decorator, which among other features can highlight source code files. The language syntax descriptions are provided via special states files. The standard distribution contains states files for the most popular languages (C, C++, Pascal, LaTeX, etc), but sadly there is no states file for R. Does anyone know if there is a place where I can obtain enscript states file for decorating R scripts? Many thanks!

Re: [R] Question about copula-GARCH model
A simple approach is to assume that dependence structure between variables (which is characterized by copula) is constant throughout the process. In this case, you may apply log-likelihood estimation of copula parameters to ranked AR-GARCH process residuals. A more complicated approach is to invent a model of how copula parameters depend on the previous values of the process. This *might* provide a better description of some empirical effects. But in reality, these models are not reliable enough, because you are likely to deal with many more parameters than in univariate case, and there is no general way to estimate the parameters of copula evolution. However, attempts are still made (see for example package mgarchBEKK).

[R] Finding dependencies and clusters in live survey data with a mix of independent variable types
I have a set of live data about customer satisfaction and desires of a live ecommerce site. There are only 311 survey responses. There were approximately 154 questions. A large fraction of these questions were questions with numerical answers (e.g. on a scale of 1 to 10 how satisfied are you with our service, how many months have you been a customer for, how old are you, how many computers do you own). A second large fraction of the questions had binary answers (e.g. do you own an ipod, do you think blogging will be more or less popular in 5 years time than it is now, do you use online video sites). The remaining data were multinomial answers (e.g. from which of these sources did you first find out about this site, which of these most closely describes the industry you are in). I am mostly interested in finding subsets of customers for whom some subset of survey answers best correlate with their answer to the question On a scale of 1 to 10, how would you rate our overall service? I am also interested in identifying market segments of like-minded individuals with similar interests and views and find out what they, as a group most want from the service in the future. I am aware of how to perform multiple linear regression using R but I am not sure how to 1. handle the binary variables and multinomial variables as independent variables 2. find a set of canonical independent variables which most closely correlate in combination to the overall service rating data 3. find market segments among the data by looking for clusters of like interests and views Are any of the above suitable for analysis by R? If so, do there exist example programs available which achieve similar things that I can study as guides? Thanks in advance for your contemplation.

Re: [R] creating a matrix subset based on a threshold cutoff
that's great, thanks
On Tue Mar 4 12:29 , Henrique Dallazuanna sent:
I think that this shoul works:
do.call(rbind, apply(as.table(x), 1, function(.x).x[any(.x cutoff)]))
Change as.table(x) by your table

You have a table or matrix?
if is matrix:
set.seed(123)
x - matrix(rnorm(100), 10, 10)
cutoff - -1.5
do.call(rbind, apply(x, 1, function(.x).x[any(.x cutoff)]))

Hi,
I have a table of x rows and y columns. The table is huge and so i'd

to create a subset of the data containing rows where any of the y

below a threshold, say 1e-4. Is there a simple way of doing this in R?

[R] R on a computer cluster
Dear all, I usually run R on my laptop with Windows XP Professional. Now I really want to run R on a computer cluster (4 processors) with Suse Linux Enterprise ver. 10. But I am new with computer cluster. Should I modify my functions in order to use the greater performance and availability than that provided by my laptop? Is there any R manual on parallel computations on multiple-processor? Any suggestion on a basic tutorial on this topic? Thank you. -- Gabriele Accetta U. O.

[R] data manipulation for plotting
Hi, i'd like to plot some data that I have with the value on the x axis and freq on the y axis. So, I need to calculate the freq a value is seen within my data vector for example, say i have a vector of data data=c(1,1,1,4,5,5,6) I want values-c(1,4,5,6) freq-c(3,1,2,1) in order to enable me to plot this.

[R] axis help
Hi, i'm having trouble with my x and y axis. The commands i'm using are below. The problem is that the y axis starts at coordinate 0,1 and the x axis starts at coordinate 0,0. As far as I know the y axis can't start at 0 (because it's log scaled) ,so I would like to position the x axis at 0,1 but don't know how to do this. Could anyone advise?

[R] integration
Dear All, I need to perform a numerical integration of one dimensional fucntions. The extrems of integration are both finite and the functions I'm working on are quite complicated. I have already tried both area() and integrate(), but they do not perform well: area() is very slow and integrate() does not converge. Are in R other functions for numerical integration of one dimentional functions?
