You say a "pdf-publication."  Pdf itself is compressed.  So when
you convert to pdf, the figure should get smaller.  Apparently
this is not happening.

You might try producing pdf directly from R instead of ps.

Or use ps2pdf on the output of R, then use pdflatex.

Or use R's xfig output and then use xfig to produce the eps (and
then convert to ps), but I'm not sure that xfig will be any
smaller.

Or make the graphs smaller using par().  Then, when you include
them in your LaTeX document, blow them up again using (e.g.) 
includegraphicx[width=4in]{...}.
