[R] Changing R_HOME

[William Thompson]

I'm trying to run multiple simulations using R on a cluster of pentiums running 
Solaris X86 by batching the R routines and simultaneously farming them out to 
the cluster nodes. This works fine on some of the machines, but on others the 
directory structure is mapped differently, so that when I try to run R, it can't 
be found, I can get around this by running /net/mp1/space/local/bin/R which gets 
me to R binary, but then I get the message: R_HOME (`/usr/local/lib/R') not 
found. I tried setting the environment variable R_HOME to the proper library 
location but then I get the message: 
WARNING: ignoring environment value of R_HOME
R_HOME (`/usr/local/lib/R') not found

I know the solution is to get the directory structure remapped, but that's not 
going to happen soon because the sysadmin is out of town and he may have good 
reasons for doing things the way he did. Is there some way to tell R to look 
somewhere other than the default location for its libraries on startup? Any 
clues or pointers would be appreciated.

Thanks
Bill
