Sure, correct. By default they are in a printing format.

If you ask for EPSF, you get an EPSF header. If you don't, you don't.
The helpful help page says

 onefile: logical: if true (the default) allow multiple figures in one
          file. If false, generate a file name containing the page
          number and give EPSF header and no `DocumentMedia' comment.

...

     The postscript produced by R is EPS (Encapsulated PostScript)
     compatible, and can be included into other documents, e.g. into
     LaTeX, using `\includegraphics{<filename>}'.  For use in this way
     you will probably want to set `horizontal=FALSE, onefile=FALSE,
     paper="special"'.

Now when I wanted this a couple of years ago it was not on the help
page, so there was a reasonable excuse (and anyway then it was not
genuine EPS) ....
