[R] pretended size postscript and size of the graphic device window

[mirca heli]

Dear list members!

I've two questions concerning graphic export:

a) I want to export my graphics as PostScript files. in this way I use the postscript() function. The tricky part is that they must have a pretended size (7 x 7 cm) and an absoulte font size (10pt).
b) how can i (permanent) change the size of the graphic device window?

Best regards
