[BioC] topTable question in limma

[pingzhao Hu]

Hi,
  I am using limma. Here is a error I met

SubM is a 19k by 6 matrix
 > design
[1]  1  1  1 -1 -1 -1
 > 
PMAfit<-lmFit(subM,design,ndups=2,spacing=1,correlation=mycor$cor,weights=NULL)
 > PMAfit<-ebayes(PMAfit)
 > 
topT<-toptable(PMAfit,number=200,sort.by="P",genelist=genelist,adjust="fdr")
Error in array(x, c(length(x), 1), if (!is.null(names(x))) list(names(x),  :
         attempt to set an attribute on NULL

Thanks
