Hi all,

My question is based on a project I have partially done, but there is still

My goal is to create a R package contains GPU functions (some are from Nividia

My design is quite different from current R's GPU package, I

I've trying to fix the check error in rpvm package. Right now on my Mac, I
use darwinport to install PVM and I can get rpvm to pass the check using 'R
-arch x86_64 CMD check'. However the default 'R CMD check' uses i386 which
fails since PVM is built for x86_64 only.
So is there a way to ensure pr

Greetings,
I have a computer with the following setup:
1)cblfs (pure 64-bit (amd64) linux), kernel2.6.34 gcc4.4.2
2)R-2.11.1
I compiled R with BLAS and lapack using the switched ( --with-blas="-
lpthread -latlas -lfptf77blas"
--with-lapack="-llapack -lcblas" ).

uses modulus 2^30. Therefore there are only 2^30
distinct numbers, which is confirmed by my previous test in R.
If someday Knuth's double version is also included in R, it will be great.

Professor Ripley,
Thank you for your solution. So the last paragraph of the Note in RNG
help page will be updated since Wichmann-Hill is different from other
supplied uniform generators in the number of distinct values?

Dear All,
I tried to write a C++ program that uses R internals and I encounter
"undefined reference" error when linking to libR.so. Here is an small
example of the program test.cpp:

Hi,
I have one question about built-in R functions. I am looking into
interprocedural analysis and since R supports "free variable", it would
become complicated if free variable is read inside a function. It is
uncommon and probably not good to read free variables when implementing R
functions. I

needing to keep them in sy
