Thank you for the reply, my problem is that i don't understand the error that
plot(ca) is giving me:
> plot(ca)
Error in matrix(as.matrix(obj), nrow = I, ncol = J) :
non-numeric matrix extent
so just to put this in context: my workscreen looks like this:

A B C
G1 1 34.00 231.0
G2 231 1.00 0.1
G3 12 0.02 23.0
