Dear all, I was playing around with some C-code that I dynamically linked to R and noticed the following inconsistency: > dat <- matrix(1,3,3) > is.double(dat) [1] TRUE > is.integer(dat) [1] FALSE > dat <- matrix(1:9,3,3) > is.double(dat) [1] FALSE > is.integer(dat) [1] TRUE How did I find out? I passed `dat' to a double * in the C-code and printed out the matrix

...le. But the usage documentation hasn't informed us about this. You can find it by excuting the following code: xx=matrix(rnorm(20*3),ncol=3) bb=c(1,2,0) yy=xx%*%bb+rnorm(20,0,10) data=data.frame(y=yy,x=xx) myformula=formula("y ~ x.1 + x.2 + x.3") cv.lm(data,myformula,m=10,plotit=F, printit=TRUE) myformula=formula("y ~ x.1 + x.2") cv.lm(data,myformula,m=10,plotit=F, printit=TRUE) myformula=formula("y ~ x.1 ") cv.lm(data,myformula,m=10,plotit=F, printit=TRUE) What happened? they give three equal mss(mean squared error). Or you can just check the code of function cv...

Dear all, I've tried a multiple regression, and now I want to try a cross-validation. I obtain this error (it must be sth related to df) that I don't understand, any help would be appreciated. cv.lm(df= dat, lm2.52f, m=3) Error en `[.data.frame`(df, , ynam) : undefined columns selected lm2.52f is my lm object, dat is a dataframe where the variables involved in .lm are I tried CVlm

...it fails, because it's illegal to have 2 graphics in a metafile. It works with pdf, but even then I get two plots, which is a nuisance. I found a workaround by using windows(); savePlot, but it only works in interactive mode, not when called with something like (Windows) rterm --no-save < printit.r Any ideas?
