[R] help with plot of prcomp object

[Kimpel, Mark William]

I need to plot a prcomp object from package stats with custom symbols suitable for B&W publication. My boss specifically wants filled and unfilled square, triangle, circle, inverted triangle, diamond to represent 5 brain regions of 2 types of rat.

Can I specify these as a parameter?

Thanks,

Mark
