[BioC] rownames in topTable and posterior probability

[Adaikalavan Ramasamy]

topTable() in limma packages returns the row numbers and it would be
useful to see the row names (i.e. Affy ID) instead. I am aware that I
may supply the 'genelist' argument but help("topTable") says :

	genelist: data frame or character vector containing gene
	 	  information. If not specified, this will be taken 
		  from the 'genes' component of 'fit'.

My usual usage is as follows

fit  <- lmFit(onebatch, design)
fit2 <- contrasts.fit( fit, cont.m )
fit2 <- eBayes(fit2)

topTable(fit2)
               M         t      P.Value         B
12358 -0.8636721 -7.585040 3.808592e-05 11.958486
48048 -0.8765769 -7.400093 7.417187e-05 11.363358
...

But I found no genes component in fit via fit$genes or str(fit). Same
goes for fit2. I doing something wrong ?

Thank you.
