Hello! I was wondering if it's possible to see the actual code of checkTmvArgs function that is part of the code for rtmvnorm (which is below - I just typed "rtmvnorm" on the prompt). I get an error: Error in checkTmvArgs(mean, sigma, lower, upper) : sigma must be a symmetric matrix At the same time I am pretty sure that the matrix I am passing as sigma is a var-covar matrix

(Sorry for the cross-post--- I wasn't sure which list is more appropriate...) Hi everyone, I've run into segfaults when using my randomForest package on large dataset (e.g., 100 x 15200) and large number of trees (e.g., ntree=7000 and mtry=3000). I'm wondering if anyone can give me some hints on where to look for the problem. The randomForest package mainly consists of two things:

Hi Community, I have a question about how to pass command line parameters to R script running in the batch mode. The problem is: there is a banch of data files which are to be processed by R script called from a web-server, i.e. in the batch mode. The web server generates data files and passes their names calling 'R CMD BATCH' one by one for every file. Now the question is how to

Hi I have the feeling, that the argument stringsAsFactors has no impact in the function expand.grid: a <- c("PR", "NC", "A2", "BS") b <- c(1, 0.5, 0.25, 0.125, 0.0625, 0.03125) class(expand.grid(css, fscs, stringsAsFactors=FALSE)[[1]]) [1] "factor" class(expand.grid(css, fscs, stringsAsFactors=TRUE)[[1]]) [1] "factor" Also, when

Hi everyone, I am fairly new to R, and I am aware that others have had this problem before, but I have failed to solve the problem from previous replies I found in the archives. As this is such a standard procedure in psychological science, there must be an elegant solution to this...I think. I would much appreciate a solution that even I could understand... ;-) Now, I want to calculate a

Dear R-devel, Last week I got several responses to my question about debugging segfaults in my code (original post below). After I changed the S_alloc() calls to Calloc()/Free(), the symptom was gone, but I was told to keep looking. So I did: o Switched to Calloc/Free. Electric Fence did not find any problem. o Put assert(index < bound); assert(index >=0); everywhere in the C routine

I've finally took the time to figure the last few bugs (that I know of). This patch will be submit to be included in a few weeks. This patch should be generic enough for portable without too much hassle. This patch mimics OpenBSD's ftp behavior. I'm not sure like that (e.g. it doesn't put / at the end of directories by default), but that is more a question for the community

The survival package, like many others, has several helper functions that are not declared in the namespace, since their only use is to be called by other "main" functions of the package.? This works well since the functions in the survival namespace can see them --- without ::: arguments --- and others don't. Until a situation I ran into this week, for which I solicit comments

Hi there, I'm having a bit of a problem while trying to create BitCast instructions. Well, first, I have some very generic functions written in C, for which I would like to make calls on another C file I'm playing with using an LLVM Pass. The simplified signature of two of these functions can be seen below: void write(void* data, unsigned b); // write b bytes starting, at address

Hi folks, Anyway, I have a main development system which is P4 based (without EM64T) and a dozen diskless Athlon 64's. I'd like to be able to compile kernel's, etc for the Athlons in x86_64 bit mode. Any idea how to arrange this? I've recompiled the src.rpm for binutils (added a single line "CARGS=--enable-targets=x86_64-linux" to the specfile) and "as

I am running R 2.8.1 on SUSE Linux. I would like to be able to set R_PROFILE to two different possibilities. One when R is called by R CMD BATCH and another any other time. Is this possible? Mark Lyman, Statistician Engineering Systems & Integration, ATK

Dear expeRts, The order in which the variables vary in expand.grid() is often unintuitive. I would like to suggest a 'method' slot for expand.grid() which requires only very little changes (100% backward compatible) and which allows one to control this order. Please find attached diffs against R-devel. Cheers, Marius ### ./src/library/base/R/expand.grid.R

Hi all, Thanks to Prof. Ripley, Prof. Gentleman, and Simon Wood (did I miss anyone?). The problem seemed to have gone away. Everyone suggested using some malloc debugger (such as Electric Fence). All I did was following half of what BDR suggested below, i.e., changing all the S_alloc() calls to Calloc() and Free(). I didn't get to try efence, and the problem seems to have disappeared! As

Dear all, I think I found a bug in utils::format.person when using style = "R" with a vector of comments. The comment section is not parsed properly. Please find below the mwe and the session info.

Hi all, Reading the wikipedia page on R, I stumbled across the following: http://fluff.info/blog/arch/00000172.htm It does seem interesting that the C execution is that much slower from R than from a native C program. Could any of the more technically knowledgeable people explain why this is so? The author also have some thought-provoking opinions on R being no-good and that you should write

The configure script runs fine, but when I compile todays alpha version of R-2.2.0 (R-alpha_2005-09-10_r35546.tar.gz) under FreeBSD 7.0-CURRENT from Sept. 4th I get the following output: ======================================================== [...] gcc -I../../src/extra/zlib -I../../src/extra/bzip2 -I../../src/extra/pcre -I. -I../../src/include -I../../src/include -I/usr/local/include
