[R] Spidergram?

This maybe a very stupid question. But,
I'm trying to figure out how to draw the so-called "Spidergram" from a set of data, say, 15 chemical elements (on horizontal axis), and the concentration of each element from 60 stations (on vertical axis). So the matrix will be 15 x 60. The values of each station will be drawn as a connected line.

So far, after spending many hours of thumbing thru the R manuals and help files, I can only draw the line for a single station, by:

>plot(log(X.1.) ~ Atomic, data=dino, col="blue", pch=16, type="b")

Any help will be very highly appreciated.
