[Bioc-sig-seq] Combining 2 GRangesList Objects Error

[Dario Strbenac]

Hello,

I'm trying to create a longer list out of two GRangesList objects and am getting an unusual error. I think it should work out OK from the information in the package reference manual.

> summary(grl)
     Length       Class        Mode 
          3 GRangesList          S4 
> summary(grl2)
     Length       Class        Mode 
          3 GRangesList          S4 
> g <- append(grl, grl2)
Error in `rownames<-`(`*tmp*`, value = c("gr1", "gr2", "gr3", "gr1", "gr2",  : 
  invalid rownames length
> g <- c(grl, grl2)
Error in `rownames<-`(`*tmp*`, value = c("gr1", "gr2", "gr3", "gr1", "gr2",  : 
  invalid rownames length

I'm using GenomicRanges 1.09 and R 2.11.1.
