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 > > cu > Philipp > - -- Rainer M.
