R help - Oct 2004 - Could anyone tell me how to extract pvalue from "lm" fitting?

Dear R people,

I have a naive question: after fitting "lm" to a data, I can't
extract
the pvalue corresponding to a specific covariate in a direct way.
Could anyone give me a hint?

Thank you very much.

Frank

Frank,

try the following, not all of which are directly relevant, but which
explain the approach. If your lm is called "my.lm":

names(summary(my.lm))
coefficients(summary(my.lm))
class(coefficients(summary(my.lm)))
coefficients(summary(my.lm))[,4]

I hope that this helps.

Andrew
