Hello,
The error message is not at all clear. Have you copied and pasted it?
Can you post a data example? Using ?dput, for instance.
dput(head(mat, 30)) # paste the output of this in a post

Rui and Berend thank you for your help

I tried with this line:
lm (ve~ su, data = mat)
I got this message:
Lm.fit error in (x, y, offset = offset = singular.ok singular.ok ...)
