>From your post it is a little bit unclear to me exactly what you want to
happen. KEGGgraph (which you mentioned), has a few vignettes that might
help you. One of them is actually about plotting KEGG pathways. You can
find those here:
It also seems that you may have some plot that you want to push into PDF
format and are unsure how you might do that. Is that right? If so,
then you should only need to do something like this:
##turn on the pdf device to start output flowing to "myfile.pdf"
##then call plot() with the appropriate arguments.
plot(Appropriate arguments here)
##then turn off that pdf device (now that you have captured the output).
I hope this helps,
