[R] snow and different R versions

[Gábor Csárdi]

Dear Luke and others,

I have many R versions on my machine and want to start a particular
one when snow builds its cluster. (The same version I start snow
from.) It seems that everything is set up correctly in
defaultClusterOptions:

> mget(ls(defaultClusterOptions), defaultClusterOptions)
$homogeneous
[1] TRUE

$manual
[1] FALSE

$master
      nodename
"maya.unil.ch"

$outfile
[1] "/dev/null"

$port
[1] 10187

$rhome
                        R_HOME > sessionInfo()
R version 2.8.0 (2008-10-20)
x86_64-redhat-linux-gnu

locale:
LC_CTYPE=en_US.UTF-8;LC_NUMERIC=C;LC_TIME=en_US.UTF-8;LC_COLLATE=en_US.UTF-8;LC_MONETARY=C;LC_MESSAGES=en_US.UTF-8;LC_PAPER=en_US.UTF-8;LC_NAME=C;LC_ADDRESS=C;LC_TELEPHONE=C;LC_MEASUREMENT=en_US.UTF-8;LC_IDENTIFICATION=C

"/home/gabor/software/lib64/R"

$rlibs
                                     R_LIBS
"/usr/lib64/R/library:/usr/share/R/library"

$rprog
[1] "/home/gabor/software/lib64/R/bin/R"

$rscript
[1] "/home/gabor/software/lib64/R/bin/Rscript"

$rshcmd
[1] "ssh"

$scriptdir
[1] "/home/gabor/.R/library/snow"

$snowlib
[1] "/home/gabor/.R/library"

$timeout
[1] 31536000

$type
[1] "MPI"

$user
   user
"gabor"

$useRscript
[1] TRUE

but snow still starts a different version, the one in /usr/bin/R. Is
this a bug? If not, how can I tell snow to start the same version, the
one that is listed in defaultClusterOptions?

Thanks,
Gabor
