You haven't really said much about your overall project, but if you

It might be better to post it to the LyX mailing list
(lyx-us...@lists.lyx.org) since you are using LyX. Anyway, the problem

What exactly is it that's worrying you? It's a problematic regression

The easiest thing is almost certainly going to be to redefine
print.aov as desired. You can get it at by typing stats:::print.aov.
Copy the code edit and then reassign it to print.aov in the global
environment and voila!

Perhaps something like:

sapply(1:40, function(n) c(gauss.quad(n)$weights, rep(NA, 40-n)))
You'll have to decide how you want the records combined but this

Hello Sean,
It appears that you can fetch it using:
summary(a)$rsq
Full code:
require(biglm)
data(trees)
ff<-log(Volume)~log(Girth)+log(Height)
a <- biglm(ff,trees)
summary(a)$rsq
summary(lm(ff,trees))$r.squared # we get the same result
To see how it is computed, have a look at:
