Hi all! my apologies if this is too elementary: I upgraded to 1.5.0. I copied my library folder on version 1.4.1 to the library folder on 1.5.0. When I try to upload a package via the menu I get this: Error in sort(.packages(all.available = TRUE)) : 1 argument passed to "sort" which requires 2. do I have to copy any other file from the previous version?. Thanks in

Hello list, any try the new memtest86 v3.2 with isolinux 3.11 cd and pxeboot? How is the proper way to chainload memtest86 I was tried: label memtest kernel memtest.bin but, nothing happens just a weird hang (my older versions of memtest hangs too). Anyway chainloading in a floppy image with memdisk on CD or pxeboot was fine but if I use memory to emulate a floppy I was not using this memory

Hello! I have a problem with integrate() in my function nctspa(). Integrate produces an error message "evaluation of function gave a result of wrong length". I don't know what that means.

Dear All, I'm using apply to do some genetic association analysis along a chromosome, with many thousands markers. For each marker the analysis is the same, so I was planning to use apply(chrom, 2, somefunction) In the specific case I do: my.results = apply(chr, 2, function(x){anova(lrm( cpstc.f ~ x + time.cpstc + age + sex + mri))[1,3]}) This is all good and well in theory, but in
