R help - Sep 2001 - glm + error

Can someone explain this error? 
I do not understand it and do not know what to do.
> v.glm.allmax<-glm(ALL.MAX~.,data=v.q.allmax)
Error in eval(expr, envir, enclos) : numeric envir arg not of length one

Thank you for your help.

What's v.q.allmax?  My guess is that it is a matrix and not a data frame.
(Perhaps we should explicitly check for that case to give a more
explicit error message.)

The obvious thing to do is to check that what you passed glm is what the
help page says is required.

BTW, since you are using a Gaussian glm, there is little (if any) reason
to prefer glm to lm.

This was exactly my fault, I am sorry in posting this simple question, but I
was not able to find the mistake by myself.
Thank you,
