it (via sfInit(parallel=TRUE, cpus=2) or mpi.spawn.Rslaves(nslaves=2)

snow and different R versions
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
