[R-sig-eco] Help obtaining f values

Hello,

I am new using the R software and I am a little concerned about an
apparently easy procedure which is done in R. When I perform a GLM
analysis, I usually get the deviance, df and p values. Nevertheless, for
publishing, reviewers require the F value. Although I have looked in
several sources I have nott been able to find it, so I wanted to know if
any of you knows how to find the exact f value using the deviance, df or p
value.

Any help will be welcome and this is an example of what I get.

Thanks in advance
