R plots pdf() does not allow spotcolors?
...An important detail that we did not take into account is that the book will not be printed in 4 colors (cmyk mode), but only 2 (black +"spotcolor"). The spotcolor we use is part of the big Pantone family. The problem is that both pdf() and postscript() offer either rgb or cmyk, but no spotcolors such as pantone. I'm afraid this constraint can't be solved at all, and we can't use R for creating these plots? I did not find any package that would extend the colormodel to include spot colors... Did anyone had a similar experience? Thanks!! Matthieu
