Hi, All;

Išve been trying to use globaltest() function whole day but one problem kept
coming up. I had a gene expression matrix made using RMA and concatenated
the whole matrix into a 54675 x 23 dimensional matrix. And I prepared
another sample class vector with the size of 23. When I ran the globaltest()
function as follows, Išve got a very odd error:

...
> sample.ok <- ... (a sample name vector with 23 elements)
> n.norm <- 4
> n.acc <- length(sample.ok) - n.norm
> cls <- c(rep(1, n.norm), rep(2, n.acc))
> gt.grp <- globaltest(rma.mat[,sample.ok], cls)
Error in app[1, ] <- c(rep(TRUE, top), rep(FALSE, bottom)) :
    number of items to replace is not a multiple of replacement length
>

The R system keeps complaining with the same message but I canšt figure out
why. There was no way I could access the source code of the globaltest so I
donšt have any clue where this error could have happened yet. Any ideas?

Thank you very much
