Dear R users, How could I managed graphics in GIF format? What I have been doing is graphics in *.ps or *.eps and after I convert them using CONVERT (from ImageMagick) but the output quality is not good. Since these graphics will be use for other users they must have a better image quality. I really appreciate any help, -- Abraço, Nilza Barros [[alternative HTML version deleted]]

PostScript is a vector format, so there may be all sorts of things going on. Just feed png() with the width and height you want for your gif and then you wont have to resize as part of the conversion process. Also, GIFs are pretty old-tech these days, so if you could persuade your other users to switch to png files, its a big win. Barry
I am guessing you are saving the plot using the menu system. If that is the case, have a look at: ?pdf ?png Generally, I like saving my graphics to pdf since it is vectorized.
