Gabor has suggested what I think is the best way to do this check, but 
in my experience, if you are doing this check then you are almost 
certainly missing some feature of R that will let you avoid doing it.

For graphs, dev.new() has been mentioned.  I would be curious to know 
when people find it necessary to do this check, other than to issue a 
system() command for some very specialized local system reason (i.e. 
something that would never be used in a package and rarely in code run 
on different computers - not just different OSs).
