You may want to look at the nws package (there are others that also help with parallel versions, but on windows, nws seems to work the best (at least in my experiance so far)).

Subject: [R] How to set up multiple spawns of R?



Sorry: resending this; didn't have a title on it.

Trying to set up multiple spawns of R
-------------------------------------------

Hi.  I'm new to the list but I have a small problem with R.  I'm trying to
set up multiple spawns of R active at the same time on an AMD with a dual
core in Vista so that I can cut down my permutation processing time. 

I've installed R in multiple places, which I thought was the correct way to
do it but whether I use installs at "C:\Program Files\R1" and "C\...\R2", or
even separately on the C: and D: drive, whenever I try to load my package
(qtl), it gives me the error message:

Error in library(qtl) : there is no package called 'qtl'

The thing is, I've installed the packagen in both places (C\...\R1 and
C\...\R2, or both the C: and D: drives) and it still gives me the message.
Does anyone know how to set up a simultaneous R spawn?  Clearly I'm wrong
about how to get it started.

Thanks,

G Perry
