[R] extract from anova

[joris.dewolf at cropdesign.com]

Mustapha,

You should tell us what fm1 actually is (which class), before we can give
you a correct answer.
It is helpfull to use str() in this case.

str(fm1) will give you the structure of fm1, and with that information you
extract any value you want.

I suppose that this is what you need:

summary(fm1)[[1]]["Residuals","Mean Sq"]
