[R] R plots pdf() does not allow spotcolors?

[baptiste auguie]

Hi,

I may be wrong, but I have the impression that tikz (a LaTeX drawing
package) can handle spot colors (that's what Google seemed to tell me
[*]). If this is the case you could output R graphics using the
tikzDevice package, post-process the output (readable, plain text
file), and eventually have LaTeX produce the pdf image with spot
colors.

Worth a try, perhaps.
