[BioC] subset of RG - limma

[michael watson (IAH-C)]

Hi

RG$weights is a matrix of values, as is RG$R, RG$G etc etc
With

RG[RG$weights>0.1,]

You are filtering RG by it's rows, using a whole matrix to subset it!

If you want to subset on the first column of weights, try:

RG[RG$weights[,1]>0.1,]

Dear all,
 
I would like to know how can I take out from my RGList all the rows where RG$weights<= 0.1
I tried this but it doesn´t work:
 
> RG[RG$weights>0.1,] 
Error in `[.RGList`(RG, RG$weights > 0.1, ) : 
        (subscript) logical subscript too long
 

Best regards
