Assunto: [R-sig-ME] SE of predictions from lme

Dear list,

could anyone point to me a method to extract SE of predictions from a lme? I have pasted the model below.

Thanks!

Eric

m06<-lme(log(Length) ~ log(Slope)+log(Width)+log(Depth)+log(Mu)+log(D)+log(Compint2)+log(Pred2)*log(Temp)+Year, data=Data, na.action=na.omit,
random=list(Strategy=pdDiag(form=~1), Method=pdDiag(form=~1), Species=pdDiag(form=~1), Station=pdDiag(form=~1)),
weights=varComb(varPower(form=~D), varPower(form=~Pred2)))
