[Apologies if this is a duplicate; I seem to be having e-mail problems.] I've also had trouble dealing with formatting issues from R to a format acceptable for journals. But I found a really useful recommendation from Cadmus, the art folks for PNAS. Here's a useful site: http://cpc.cadmus.com/da/tutorials.jsp and http://art.cadmus.com/da/instructions/ps80_win.jsp They're not specific to R, but there's some good general advice. I, too, tend to save images as a .pdf (specificying final size and resolution), and then convert to TIF or EPS using the following (also advised from Cadmus): For EPS: Once you have a PDF file, you can open it with the ?full? version of Acrobat and then do a ?Save as EPS? ? or ? you can open your PDF with Illustrator and then ?Save as EPS.? For TIF: Open the PDF file from within Photoshop. This will allow you to determine resolution (typically, 600 DPI is ideal for most figures). While in Photoshop, go to the menu and click "Layer>Flatten Image", crop (trim) excess white space around the figure, scale it to the correct size, and then "Save As " a TIF file using LZW (not JPEG or ZIP) compression. This usually works for the journals I've dealt with. And a benefit of saving directly as PDF is you can use the alpha functionality in color.palette() to set transparency, which is really useful when having overlaying colors. (To my knowledge, alpha is not allowed when plotting in the R window.) Phil
I'd like to hear from the list, how folks specify and export presentation quality and publication quality graphics with R. I've had problems when exporting graphics using the copy-to-clipboard option (both bitmap and metafile) and also when saving them as jpgs. They almost always seem to look a little funny (e.g. pixelation, symbols coming out distorted etc.). The only option that I've had much success with is saving them as pdf's, but that format is less than ideal when trying to incorporate a graphic into another document (e.g. Word or Powerpoint), and is often not the format requested by journals.
