Hello,

 I have just completed my analysis of microarray data using limma. But, when I
ask for a list of topTable genes, I am getting the following error:

 topTable(fit2,coef=5,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

 Here, fit2 is got after ebayes fit to 'fit'. The "fit2"
object is not empty, because the attribute "p.value" is of size
20000x11.  Can someone please tell me what am I doing wrong, and how to get the
top ranked genes in this case?

 Thanks,
 Shireesh Srivastava
