300 dpi and eps:

-----BEGIN PGP SIGNED MESSAGE-----

Everything works fine to place them in a pdf file , or eps file, but
when it comes to have a high quality of 300 dpi these graphs are not
good. For example I open the eps file with Adobe Illustrator (AI)
and it shows that it is a 72dpi graph.

This is simply not true: it's an eps and thus of essentually infinite
resolution for all practial purposes. 

Just to clarify this: eps / ps are vector formats - i.e. it says in the
file "draw a line from point x to point y". In contrast, bmp (and e.g.
jpg, png, tiff) are raster formats: in these formats save the PICTURE of
the line from point x to y.
Consequently, only raster formats have dpi ("dots" per inch).

So your problem is not with 
the R-generated eps but somewhere downstream from that. Any
postprocessing, conversion or editing?

Or in Adobe illustrator? It strikes me, that 72dpi is usually the screen
resolution.

Cheers,

Rainer
