...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...

Note that the label has been truncated on chunk2 (should be getFDR) but is not affected on chunk3. Also note that chunk4 has not been expanded properly. ################################################### ### chunk number 2: getF ################################################### x <- 1 ################################################### ### chunk number 3: getFDX ########################...

...eX and metafont sources to see what I mean). I seemed to remember that a code chunk could be defined piecewise, like in Comments... <<Chunk1, eval=FALSE, echo=TRUE>>= SomeCode @ Some other comments... <<Chunk2, eval=FALSE, echo=TRUE>>= MoreCode @ And finally, <<Chunk3, eval=TRUE, echo=TRUE>>= <<Chunk1>> <<Chunk2>> EndOfTheCode @ That works ... as long as SomeCode, MoreCode and EndOfTheCode are self- standing pieces of R code, but *not* code fragments. You can *not* intersperse comments in, say, a function body, or local() environ...

...variance estimate in the same single pass over the data. Assuming I haven't messed up the package checking it will appear in the next couple of day on CRAN. The syntax looks like a <- biglm(log(Volume) ~ log(Girth) + log(Height), chunk1) a <- update(a, chunk2) a <- update(a, chunk3) summary(a) where chunk1, chunk2, chunk3 are chunks of the data. -thomas ______________________________________________ R-help at stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
