[Bioc-sig-seq] GRangesList with duplicate names

[Dario Strbenac]

Hello,

It is possible to create a GRangesList with duplicated names, but not to re-order it.

> summary(grl)
     Length       Class        Mode 
          3 GRangesList          S4 
> names(grl) <- c("Cancer", "Cancer", "Normal")
> grl[3:1]
Error in `rownames<-`(`*tmp*`, value = c("Normal", "Cancer", "Cancer")) : 
  duplicate rownames not allowed
