[BioC] limma object column subsetting

[Matt McCall]

In the old limma, one could subset a MAlist or RGlist (let's say RGnorm 
is a MAlist) by entering:
RGnorm[,1:3] for the first three columns for example
In the version, I'm using now (v1.8.1) this no longer works.

 > RGnorm[,1]
Error in object$targets[j, , drop = FALSE] :
	incorrect number of dimensions

Can someone help me with this. I'm running R v2.0.0
