It's a vector containing the names of the significant genes.

E.g., matrix(list.siggenes(data.out,delta)). But I don't think that this
actually is what you really want to have.

If your data set is called data and (as you have said) the first column of
data contains the gene names, then one way to do this is
R> data<-data[,-1] # this step is actually not needed
