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

Hi, everyone When I was using cv.lm(DAAG) , I found there might be something wrong with it. The problem is that we can't use it to deal with a linear model with more than one predictor variable. 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)

Dear R-list, I'm not sure what I've found about a function in DAAG package is a bug. When I was using cv.lm(DAAG) , I found there might be something wrong with it. The problem is that we can't use it to deal with a linear model with more than one predictor variable. But the usage documentation hasn't informed us about this. The code illustrates my discovery: > library(DAAG)

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

Dear UseRs called Hadley, or Paul, I am trying to print an edited ggplot2/grid graphics to a metafile. With the commented line below it works, but when I edit the plot by uncommenting the line, 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

I''m playing around with Rails, and I can''t get this to work. I just can''t seem to wrap my brain around it. I''m having some trouble doing an Ajax navigation column. Here''s what I have: view layout: <div id="navigation"> <%= render(:partial => "navigation", :collection => @categories) %> </div> My

The R-1.2.1 builds have gone fairly smoothly on most of my UNIX architectures, but there were many warnings reported by the picky SGI compiler that could be eliminated in future releases. Generally, I have found the SGI compilers very helpful in ferreting out portability problems, unused and/or obsolete variables, unexpected datatype coercions, etc., and they compile faster than any other
