[R] variance explaine by each term in GLS model

[Debbie Russell]

Dear all

Sorry to bother you.

I have a GLS model:

modela<-gls(pop2~pop1-1 + ccs + pop1:ccs,data=data2,corr = corSpher(c(5, 0.5 
),form = ~ latitude + longitude, nugget = TRUE), method = "ML")

I was wondering how I can work out how much variance is explained by the model
AND by each term.

Any help would be much appreciated.
