How to put nice R graphics into powerpoint
Denis - I use the following rather convoluted method with OS 10.3.8, Illustrator CS, and R2.0.1. command-c copies a figure from the quartz window. Open this file in preview and export it as a pdf file (don't know why i do this....). use illustrator, and the command <place> from the file menu to insert it in a new document. Choose <save for microsoft office> from the file menu in illustrator. this produces a png file that plays nicely, cross platform, with Word and PP. variations abound, but the goal is to get something presentable in illustrator and use its save for office option..... I noticed that preview has a png choice from export, but I've not yet played around with its options to see if I can get the same quality that the save for Microsoft Office option produces in Illustrator.

Hi, I really like the nice vector-based pdf graphics I get in R. However, PowerPoint seems to be unable to read them as vector graphics and rasterizes them, making them quite "fuzzy" and ugly. Granted, the problem lies with Microsoft, but in the mean time what is the best workaround? I'd like to do better than producing png from within R (especially that only my iMac has X11, my very old PowerBook does not). I am still able to show vector graphics in pict format in PowerPoint. So it should be possible to extract the vectorized plot from the pdf and save it as pict, still vectorized. However opening the R-produced pdf in Illustrator and saving as pict produces a file quite a bit bigger than the original pdf, suggesting it was saved as raster pict instead of vector pict. It shows up in Powerpoint just as ugly as if it was inserted directly as pdf. This is true with Illustrator CS (aka v11 I think) used either under 10.2.8 or 10.3.7. It is also true when using GraphicConverter 5 and Preview (Jaguar's version, I think it is also true with the Panther version) to go from pdf to pict. I fired up Canvas (old, version 8) and it did manage to save something that was vectorized (i.e. very sharp when viewing at 400% in PowerPoint) but the empty circles I used as symbols were not filled blacks, the dashes of dashed lines had become "wiggly", text orientation was unacceptably changed, etc. etc. So does anyone know of a technique to produce vector graphics that insert nicely in PowerPoint, either directly from R or by converting a pdf produced by R into something else?
