[Bioc-sig-seq] GRanges, RangedData coercion

[Ivan Gregoretti]

Hi all,

Is it possible to coerce a GRanges to RangedData?

Apparently, it is not:

> class(P)
[1] "GRanges"
attr(,"package")
[1] "GenomicRanges"
> as(P,'RangedData')
Error in as(P, "RangedData") :
  no method or default for coercing "GRanges" to "RangedData"

Am I missing a library?

Thank you

Ivan
