Yes.  Most easily, use GSView on Windows, which has a menu option to 
do this.  The same author (Russell Lang) has a standalone program epstool
that can add (or remove) previews.  That has a Unix version, but whether it
can add on Unix previews that Word can read, I don't know.

GSView/epstool are found on ghostscript sites, once under rjl, now I think
under ghostgum.

The only vector graphics formats supported by R on Linux are PostScript and
XFig to my knowledge.  We do hope to add PDF and WMF one day but the latter
in particular is not going to be easy due to lack of documentation (and
lack of existing convertors).
