Hi All, I recently found gmane http://gmane.org/ It's a system to covert mail to news and back, with the nice property of keeping a searchable archive... Very convenient if you are subscribed to many lists and don't want to have your mail box cluttered. I use it to read several mailing lists already, but R is not available there. I wonder if the admins know about gmane and if they

Hi All, If you use vim to edit R code, you may be interested in this. I have put together a personalized syntax file, some code templates, and a way to send code from Vim to R using autoHotKeys (windows). http://www.andrew.cmu.edu/user/jquesada/RvimSuite/instructions.html Actually, the little autoHotKeys can be useful even if you don't use vim just to send the example R code from the help

(Extremely sorry, disregard previous email as I hit send before pasting the latest version of the example; this one is smaller too) Dear R users, I want to apply a function that takes two vectors as input to all pairs (combinations (nrow(X), 2))of matrix rows in a matrix. I know that ideally, one should avoid loops in R, but after reading the docs for do.call, apply, etc, I still don't know

Dear R users, I need to normalize a bunch of row vectors. At a certain point I need to divide a matrix by a vector of norms. I find that the behavior of Matrix objects differs from normal matrix objects. Example the following code examples differ only in xnormed changing from normal to Matrix object: x = matrix(1:12,3,4) x = as(x, "CsparseMatrix") xnorms = sqrt(colSums(x^2))

Dear all - I do fret this to be a revealing beginner question - fortunately, this mailing list have been good to me in the paste .-) I am looking for a good R editor/environment in ubuntu. To that end, I have decided to dive into gvim as the modality offered here seems to make sense for editing. I want to use Johannes Ranke's vim r-plugin, but I can't make it work. I have the plugin

Dear R users, People who uses vim in Linux/Unix may be interested in checking the plugin for R that I'm developing: http://www.vim.org/scripts/script.php?script_id=2628 The plugin includes omni completion for R objects, code indentation and communication with R running in a terminal emulator (xterm or gnome-terminal). This last feature was already present in Johannes Ranke's plugin.

Hi, I need to multiply all columns in a matrix so something like apply(x,2,sum), but using multiplication should do. I have tried apply(x,2,"*") I know this must be trivial, but I get: Error in FUN(newX[, i], ...) : invalid unary operator The help for apply states that unary operators must be quoted. I tried single quotes too, with the same results. Thanks, -Jose -- Jose

Hi, This is a simple trick to get autoclose parenthesis on windows. If you like how StatET autocloses parens, but like to use the lighter Vanilla R, you can use autohotkey (http://autohotkey.net) to provide this functionality. Simply put the below code in a text file, rename extension as .ahk and doubleclick on it to execute. ------------------ code starts here 8< ------------------ ;

Hi, Has anyone run any R vs Python (numpy) tests? I'd love to see what the differences performance-wise are, specially handling large sparse matrices. Since both rely on external C code, there might not be much of a difference. If you know and use both languages, what are the main differences and what made you stick to one over another? I also noticed that there are strong libraries

Hi, I was wondering if anyone has had good experiences using R on Linux with dual AMD64 (Opteron) processors. I'm thinking of buying a couple of such servers, but I'd like to make sure R would work fine. The "R Installation and Administration" guide notes that there may be some problems with BLAS libraries. That's all I could find about R on AMD64. Please share your

Hi, I'm attending summer School at UCLA (IPAM) on "probabilistics models of cognition". I have been an R-user since v. 1.4.1, but was trained in the frequentist tradition (as most psychologists!). I found that all faculty here use matlab and Murphy's bayes net toolbox. I have not had the need to use matlab before, and would love to stick to R for graphics models and

Hi, I'm running this for a simulation study, so many combinations of parameter produce many predictions that I need to correlate with data. The problem ---------------- I'm using rating data with 3 to 5 categories (e.g., too low, correct, too high). The underlying continuous scales should be normal, so I chose the polychoric correlation. I'm using library(polychor) in its

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, A follow up to my previous post. It'd be good to have syntax highlighting in the html help pages. There is highlight (http://www.andre-simon.de/) which seems to be open source. Since code is delimited in the help file format, it should not be too difficult to run a highlighting program (actually, vim and emacs do this too) recursively and

Hi, I got the following error. Sorry but this time I couldn't reproduce it with a simple chunk of code: .TM.repl.i.2col(): drop 'matrix' case ... Error in .nextMethod(x = x, i = i, j = j) : 'i' has no integer column number should never happen; please report In addition: Warning messages: 1: Ambiguous method selection for "%*%", target

Hi, Is there any simple solution to get ranks in descending order? Example, a <- c(10, 98, 98, 98, 99, 100) r <- rank(a, ties.method="average") produces 1 3 3 3 5 6 I would want this instead: 6 5 3 3 3 1 Note that reversing r doesn't work but in small examples. Thanks, -Jose -- jquesada at andrew.cmu.edu Research associate http://lsa.colorado.edu/~quesadaj Dept. of

Hi, I'm finding that readMM() cannot read a file written with writeMM(). Example: library(Matrix) a = Matrix(c(1,0,3,0,0,5), 10, 10) a = as(a, "CsparseMatrix") writeMM(a, "kk.mm") b = readMM("kk.mm") Error in validObject(.Object) : invalid class "dgTMatrix" object: all row indices must be between 0 and nrow-1 Thoughts? Thanks, -Jose -- Jose

Hi, While I'm a devoted vim user, I'm testing ESS :) How do I set the working directory when using ESS and R under windows? When I try to launch R, it asks for a directory. In windows, it simply doesn't let you pick a directory on the 'open' dialog. It may be a problem with windows server 2008 64 bit, though, as it seems really basic. Thanks. Best, -Jose -- Jose Quesada,

Dear R-WinEdit users, I got a simple question, but somehow I cannot find the answer, although I have tried a lot! I got an ASCII-file and I want to import it into R, so that every character is defined by [i;j]. The rows are not of the same length. the file looks like the following shortened abstract example: name: xxxxx xxxx age: 9.9.99 record number: 999 title: xxxxx xxxx xxx keywords: xxx xx

I am trying to get the Vim-R-Plugin<http://www.vim.org/scripts/script.php?script_id=2628> to work with gvim and R on Windows 7. When I open a .R file in VIM, it complains and says ""Python interface must be enabled to run Vim-R-Plugin." I have installed pywin32 for python 2.7, and added the following 4 lines to my _vimrc per the instructions
