There is the "version" (a list) variable:
version
# platform i486-pc-linux-gnu
# arch i486
# os linux-gnu
# system i486, linux-gnu
# status Patched
# major 2
# minor 4.0
# year 2006
# month 11
# day 25
# svn rev 39997
# language R
from which you can extract the "os" component:
version$os
# [1] "linux-gnu"
I don;t know what this says on a Windows system,
but it surely won't mention Linux!
So testing this wil enable you to set a flag, e.g.
Linux<-ifelse(length(grep("linux",version$os))>0, TRUE, FALSE)
if(Linux){window<-function(...) X11(...)} else
{window<-function(...) windows(...)}
Hoping this helps,
Ted.
