R-1.3.0 is released - R-help

Hi Peter,

Re ATLAS:

Matrix multiplication functions %*% and crossprod() now use a
        level-3 BLAS routine dgemm.  When R is linked with the ATLAS
        or other enhanced BLAS libraries this can be substantially
        faster than the previous code

I have just installed ATLAS under my home directory on my Sun Ultra 5
(Solaris 8); how do I link these libraries to R-1.3.0? (I probably want
to know this before I install it :) If I add the ATLAS library path to
my LD_LIBRARY_PATH, will this be sufficient?

Thanks in advance for your help,
Dennis

I have in .Rconf in my home directory:

CFLAGS="-Wall -g -O3"
FFLAGS="-Wall -g -O3"
LIBS=-L/home/pd/ATLAS/lib/Linux_K6III

putting the same stuff in config.site in your build directory works
too.

Hi all,

Speaking of BLAS and enhanced BLAS libraries, does anybody know how
link R to the Sun Performance Library (that includes BLAS, LAPACK
etc.)? I tried once unsuccesfully, and I want to give it another try
when upgrading to 1.3.0. I work on a Sun Ultra 60.

Thank you in advance,
Giovanni Petris

The point is: use LIBS and not LD_LIBRARY_PATH or equivalent.
See `R Installation and Administration' in R 1.3.0.
