[BioC] EdgeR: Problem with selection of highest transcript

Hello, when I use this (from carcinoma vs normal example), I select only the lowest transcript instead of the higest:
> o <- order(rowSums(y$counts))
> y <- y[o,]
> d <- duplicated(y$genes$Symbol)
> y <- y[!d,]
> nrow(y)

what is wrong ?
I am a novice in informatics.
and I do not know how to save my list of genes (for example after the carcinoma vs normaltissue example).
many thanks,
Best regards,
