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
