There is the "version" (a list) variable:


# 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:

# [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,
