[R] plot.prcomp() call/eval

[Jessica Streicher]

Well, i built the methods to create a bit of latex and plot to pdf files for figures, especially figures with subfloats, which weren't possible with sweave (at least i didn't find a way). So i only have to make the calls, give them to the method, and will get proper latex, and the plots will be saved to files.

I'm saving several lines of latex and several lines when creating the file each time i use it, and i use it often.
