[R-SIG-Mac] Problems with savePlot() and postscript under Snow Leopard

[Hannes Nietnagel]

Thanks David for your reply!

> dev.off()

That works fine for the png. But I still get the message:
postscript
        3

What does it mean? Is there something wrong with my postscript? I
still cannot produce a decent .eps file.

Thank you!

Hannes
