Re: [R-sig-eco] Extracting information from lm results

Hi Steve,

you can extract this information from the summary of your linear
regressions, i.e. summary(lm1).

e.g.

sum.lm1=summary(lm1)
sum.lm1$coef[2,2]    #this gives you the SE of the slope
sum.lm1$r.squared    #this gives you the R2
and so on...
This should be clear from a look at str(sum.lm1).

Hope that helps,

Christoph
