[R] How to put 2 or more graphics in the same page ?

[Aurelien de Reynies]

Hi,

I have a naive question...

I have produced about 60 graphics and want to put them in one postscipt
file ,  possibly 4 graphics on each page. I can put all of them in the
same file (that's ok), but I can't find the way  to put 2 or more
(precisely 4, in my case) graphics on the same page (each graphics is
about 6 inches (width) X 4 inches (height)).

Any help would be very much appreciated...
