[R] probleme with savePlot (to eps)

[David Winsemius]

So I guess the question to be answered by the OP now is what code he  
was using and what machine specifics he is working with.

The bottom of my savePlot help page says [Package grDevices version  
2.8.1 Index].

Is the difference due to our respective platforms (here Mac 10.5.6,  
sessionInfo below) or to a difference in versions?
