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.
