first of all, I'm not an expert on R, I'm still learning, so sorry if this is a stupid question...
I have a large dataset that is to big for my computer memory, and I found quite useful the package biglm. Now everything is working perfectly. But if I want the residuals, how I can do it?
Let's say that we are running the example:
 
> data(trees)> ff<-log(Volume)~log(Girth)+log(Height)> > chunk1<-trees[1:10,]> chunk2<-trees[11:20,]> chunk3<-trees[21:31,]> > a <- biglm(ff,chunk1)> a <- update(a,chunk2)> a <- update(a,chunk3)> > summary(a)Large data regression model: biglm(ff, chunk1)Sample size =  31               Coef   (95%    CI)    SE p(Intercept) -6.632 -8.231 -5.032 0.800 0log(Girth)   1.983  1.833  2.133 0.075 0log(Height)  1.117  0.708  1.526 0.204 0
Now, how I can obtain the residuals ?
 
Thanks in  advance,
 
Giulio
