[Bioc-sig-seq] GRanges In Development Version

[Dario Strbenac]

Hello,

I've installed the development versions of IRanges - 1.7.34 - and GenomicRanges - 1.1.25 - and now the copying and pasting of the constructing a GenomicRangesList example in the Reference Manual doesn't work. Is there an implicit dependency on R 2.12 maybe ?

> gr1 <-
+ GRanges(seqnames = "chr2", ranges = IRanges(3, 6),
+ strand = "+", score = 5L, GC = 0.45)
Error in which(lengths == 0L) : 
  could not find symbol "useNames" in environment of the generic function
> gr2 <-
+ GRanges(seqnames = c("chr1", "chr1"),
+ ranges = IRanges(c(7,13), width = 3),
+ strand = c("+", "-"), score = 3:4, GC = c(0.3, 0.5))
Error in which(lengths == 0L) : 
  could not find symbol "useNames" in environment of the generic function
> gr3 <-
+ GRanges(seqnames = c("chr1", "chr2"),
+ ranges = IRanges(c(1, 4), c(3, 9)),
+ strand = c("-", "-"), score = c(6L, 2L), GC = c(0.4, 0.1))
Error in which(lengths == 0L) : 
  could not find symbol "useNames" in environment of the generic function
