At least for R 2.3.1, neweS requires that all of the variables have "names"
that correspond to the "colnames" of the matrix. That's fine, I know about
that, and I use a modified version of neweS that puts the names in there. It
works well with data from most sources.
However, we tried reading in the matrix from a text file, and again get an
error that says sampleNames differ from phenoData rows. What's going on?
Modified neweS:
"neweS" <-
function(mat, vlist, vlabel=as.list(names(vlist))){
names(vlabel)=names(vlist)
#Must add appropriate names to the variables in vlist for R 2.3compatibility.
for (i in 1:length(vlist)) {
names(vlist[[i]]) <- colnames(mat)
}
###
pdata <- new("phenoData", pData=as.data.frame(vlist), varLabels=vlabel)
eset <- new("exprSet", exprs=as.matrix(mat), phenoData=pdata)
return(eset)
}
I believe this is identical to the existing neweS except for the part
between the #s.
We're stumped here, I'm grateful for any ideas!
Thanks
