[R-sig-eco] extracting variance components from lm

[Lee, Laura]

Hi all-

I have a fairly simple model:

m1 <- lm(Catch ~ Year + Station + Year*Station, data = data)

I would like to extract the among years and year*station variance components and need assistance. I'm aware of the 'varComp' package, but I believe that only applies to nlme and requires a random effect. Any help is greatly appreciated. Thanks!


Cheers,

Laura
