yet another fast BLAS (from AMD this time)
Dear R-devel, Has anyone played with this? http://www.amd.com/us-en/Processors/DevelopWithAMD/0,,30_2252_2282,00.html <http://www.amd.com/us-en/Processors/DevelopWithAMD/0,,30_2252_2282,00.html> .

Lwd ignored when printing on Windows
Dear R-help, Has anyone notice the problem that, on Windows (NT and XP), when printing a graph using the "File -> Print..." menu in the graphics window to print the graph, that line width seemed to be ignored in the printed output? For example, if I make a plot with plot(1:10, type="l", lwd=5), it looks right on screen, but when printed out using the menu, it looks like

undocumented objects in a package
Dear R-devel, I recall that there used to be a mechanism to get around the requirement that all objects in a package have associated documentation; i.e., a way to specify a list of objects (mostly functions) that are not considered as part of the package API. Is this still available? I cannot find any mention in R-exts. I realize that the way to go is to have a name space, and eventually

how to exclude terms preceded by - from model frame
[I believe few users manipulate formulae and model frames like this, so I'm posting here instead of R-help.] I just found out that model.frame() includes all terms, including those preceded by "-" in the formula, in its output (as mentioned on its help page). Is there a recommended way of excluding "negative" terms? My guess is that I can use info in the terms attribute

compilers for R on AMD64
Dear R-devel, A while ago Prof. Ripley had mentioned that g77 on AMD64 isn't the greatest, and the Salford Fortran is likely to be better. My question is, has anyone tried compiling R with Salford compilers (or other commercial compilers)? If so, do they offer performance advantages over GCC? TIA for any info.

Problem when making refman.pdf on WinXP (R 1.7.1)
Dear R-help, Can some one tell me what could be the problem? I downloaded the R-1.7.1 source and try to compile it on WinXP. "make", "make bitmapdll", "make tcl", "make recommended" all ran w/o problem. However, when I ran "make docs", it failed at creating refman.pdf, with no apparent error that I could see. I have attached the log file

help diagnosing ftp problem
Dear R-help, I've been compiling R from source on our Linux boxes for quite a while. One thing that bugs me is that I always get an error when make check-all where it choked up running tests/internet.R. That wasn't a big deal, as I can run install.packages()/update.packages() fine, and that's all I use the 'net connection for. The problem is that it takes a _long_ time to fail

strange error from R CMD check about xaxp
Dear R-devel, Kurt had alerted me to the problem that the randomForest package that I maintain has been failing checks in R-devel. However, I just can't see why or where it's failing. I'd very much appreciate any pointer. The failure occur when running the example code in varImpPlot.Rd: > varImpPlot(mtcars.rf) Error in par(opar) : invalid value specified for graphical parameter

R on Linux/Opteron?
Dear R-help: Has anyone tried using R on the the AMD Opteron in either 64- or 32-bit mode? If so, any good/bad experiences, comments, etc? We are considering getting this hardware, and would like to know if R can run smoothly on such a beast. Any comment much appreciated.

make check-all does not find DESCRIPTION for VR packages
When running make check-all on R-1.9.0beta (2004-03-31) built with pgf77/gcc/g++ on the Opteron (running SLES8), I get four warnings about not finding the DESCRIPTION files for the packages in the VR bundle; e.g., cannot open file `/u1/scratch/R-1.9.0/tests/Packages/VR/spatial/DESCRIPTION' Error in tools:::.checkPackageDepends(dir = "/u1/scratch/R-1.9.0/tests/Packages/VR/spatial")

speed difference between pgf77 and g77 on amd64
For those interested: I compiled R-1.9.0beta_2004-04-02 with pgf77/gcc/g++ and g77/gcc/g++, both _without_ fast BLAS. Both passed make check-all. Simple crossprod(m) for fairly large `m' shows that the version compiled with pgf77 is about 15% faster: [andy@leo:scratch]% echo "set.seed(1); m <- matrix(runif(5e7), 1e4); gc(); system.time(crossprod(m))" | R-1.9.0-PGI/bin/R

delay of warning for things in .Rprofile
Hi all, I was playing with R-devel 2005-03-08 on winXP Pro (installed from Duncan's installer). My .Rprofile contains: options(defaultPackages=c(getOption("defaultPackages"), "mypkg"), chmhelp=TRUE) but "mypkg" has not yet been installed in the library/ directory of this installation. When Rgui starts, I do not get any error or warning, but upon

meaning of "trim" in mean()
(I see this in both R-patched r43124 and R-devel r43233.) In the Argument section of ?mean: trim the fraction (0 to 0.5) of observations to be trimmed from each end of x before the mean is computed. Values outside that range are taken as the nearest endpoint. Then in the Value section: If trim is non-zero, a symmetrically trimmed mean is computed with a fraction of trim observations

dot in function name taken as S3 method by package check
Hello everyone, I'm trying to update the locfit package so that it passes package check in R 2.6.0. However, the check seems to think some of the functions with dot in the names are S3 methods (thus warns about the format of the \usage{} part) when they are not. Can anyone recommend a workaround for this? I tried reading R-exts, but couldn't find any hint. I'd very much appreciate

problem with the installed R script
Dear R-help, I had a problem running a Perl script on AIX inside pipe() or system(). The Perl script was not finding some modules when run from within R. The sysadmin tracked it down to a problem with R_LD_LIBRARY_PATH in the installed /usr/local/bin/R script: original: : ${R_LD_LIBRARY_PATH=${R_HOME}/bin:/opt/freeware/lib:/usr/local/lib:/opt/free

configure stuck in checking leap seconds (R-1.8.1 on AIX)
Dear R-help, We've been trying, so far unsuccessfully, to compile R as 64-bit under AIX 5.1. Following the recent post by Dr. Christoph Pospiech, I started with R-1.8.1 and manually edited the configure script according to the .diff file. Part of the diff has: *************** *** 24446,24452 **** int main () { struct tm *tm; ! time_t ct; ctime(&ct); ct = ct - (ct

conditional import in NAMESPACE
Dear R-help, Can some one tell me if it's possible to have conditional importFrom() in the package NAMESPACE file? Basically I'd like to know if it's possible to make the NAMESPACE file compatible with R 1.9.0 and those 1.8.1 and earlier. The problem is that I want to import cmdscale(), which is in `mva' prior to 1.9.0 but in `stats' post 1.9.0. Any pointer much appreciated!

can I have a matrix of factors, please?
Dear R-help, Is it a violation of the S language to have a matrix of factors? What I would like to have is just a factor object that has dim attribute, and can be printed (and subsetted) like a matrix; i.e., all columns/rows have the identical levels. However, I can't get it to work: > x <- factor(sample(2, 10, replace=TRUE)) > dim(x)<- c(5,2) > x [1] 1 2 2 1 2 1 1 1 2 1

a plead to package developers regarding GCC
Dear DevelopeRs, I'd like to ask those who develop R packages with compiled code to please try avoiding dependency on GCC (gcc/g77/gfortran/g++) specific features in the code, for the simple reason that there are non-GCC compilers out there that might choke on such features. I found this out back when I was trying to build R-2.3.0-to-be on our dual Opteron based Scyld cluster. Because the

suggesting a new feature for unique()
Dear R-devel, May I suggest that a new feature be added to a couple of unique() methods? Sometimes it's useful to have the indices of the original data that the unique elements come from, so that the original data can be recreated from the unique()ed data. I suggest that an `index' argument be added for unique. Below is a suggested patch against R/src/library/base/R/duplicated.R: ***
