R-beta: edit figs with xfig?

[Bill Simpson]

Question for R users under unix:
Do you ever edit figs created by R using xfig or some other program?  I
tried to edit a figure with xfig (a program which I find quite horrible by
the way) and it said it couldn't read it in.  I guess xfig has no
capability of reading postscript files?

Can anyone tell me how to do it, or perhaps suggest another freeware
structured drawing program for use in touching up postscript figs output
by R?

Thanks very much for any help.
