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

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

problem compiling R-1.9.0beta with PGI compilers on amd64
Dear R-devel, I'm trying to compile R-1.9.0beta (2004-03-31) with the PGI compilers (15-day free evaluation: after the 15 days the binaries will stop working). I'm running into some problems, that I hope some can offer pointers. 1. After configure, the FLIBS include /usr/local/lib' --- note the extra '. I had to manually delete it in a couple of places.

(low level) profiling of code
Dear R-help, Can some one tell me how to profile compiled code dynamically loaded into R? Here's what I tried on our dual Opteron running SUSE Linux Enterprise Server 8 (GCC 3.3): Start with R-patched dated 2004-06-07: (I also had MAIN_CFLAGS="-pg" in config.site.) R is now configured for x86_64-unknown-linux-gnu Source directory: . Installation directory:

make check failed for R-1.9.0alpha (2004-03-16) when link against Goto's BLAS
Dear all, Has anyone seen the same problem? I tried compiling R-1.9.0 alpha (2004-03-16) on our Opteron box running SUSE Linux ES8. I ran: ./configure --enable-R-shlib --with-blas=goto and got: Source directory: .

FLAC status
Hi, How's the testing going? I compressed 194 individual .wav files (totaling 8.54GB) which contained tracks ripped from many varied albums. I unflacced them and compared their md5 signature with the same from the original .wav. They were all perfect. I didn't use the -V option just in case of any chance of mis-reporting. I hope to test it with the complete collection of ~41GB

RGui (Windows) crashes after use of a Salford Fortran DLL
Anybody out there successfully using the Salford Fortran compilers with R? I have created a DLL using the Salford FTN95 compiler and it works in as far I can dyn.load it, run the routines and get the right answers back. Unfortunately subsequently, sometime later, the Rgui crashes (access violation I think from the DrWatson log). The crashes depend on whether or not I paste the code as one

debugging strange segfault
Dear R-devel, Can anyone give me some hints on how to go about debugging a strange segfault in my randomForest package? Here's the scoop: A user reported segfault when running predict() in the randomForest package. I asked for the data and code. The combination runs fine under WinXPPro, but does give segfault on one of our Linux boxes running R (1.7.0 through R-devel_2004-01-08) on

fSeries Garch and Arfima Ox interface
Hello all, This is a request for help from somebody who has the Ox interfaces working in R. I am trying to get the Ox interfaces working for Arfima and Garch modelling. However, I am having several problems: 1. The link to download G at rch_v40 does not work. Does anybody have a copy to email to me please? 2. Various guides offer different instructions for installing Ox in the correct place

Running R [Broadcast]
In the R-2.3.0 directory, what do you get if you type bin/R? Does R starts up OK, or do you get an error? What were the last few lines of output from running configure?

strange results with dmvnorm
I am experiencing strange results using dmvnorm. I define a scaled distance matrix from the coordinates bellow and then calculate a covariance matrix using a spherical correlation function. Then with certain combinations of range and sill parameters dmvnorm is returning values greater than 1. Surely the results of dmvnorm should be in the interval 0:1 (or do I just nead a holiday?).

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.

DLLs and the Floating Point Control Word.
Greetings. One for the developers I guess... I am having problems in using a (non-recommended) Fortran compiler (Salford ftn95 Windoze), and the crashes do seem to be associated with the ftn95-dervived DLL changing the Floating Point Control Word. The compiler people are suggesting (and I paraphrase!) that if R minds what the FPCW is it is up to R to make sure it is the value it wants and

Recursive partitioning algorithms in R vs. alia
Dear R-helpers, I had a conversation with a guy working in a "business intelligence" department at a major Spanish bank. They rely on recursive partitioning methods to rank customers according to certain criteria. They use both SAS EM and Salford Systems' CART. I have used package R part in the past, but I could not provide any kind of feature comparison or the like as I have no
