Hi, I'm frequently faced with the need to convert a regular list of

this is
not very convenient when x is a long list. I searched around but I
couldn't
find anything about this topic. Am I missing something obvious? Help
anyone?
What version of IRanges are you using? I have v.1.5.4 installed right
now and this works for me:
R> il <- list(IRanges(start=c(1, 5, 30), end=c(20, 30, 50)),
IRanges(start=c(100, 200, 300), end=c(110, 210, 310)))
R> IRangesList(il)
CompressedIRangesList of length 2
[[1]]
IRanges of length 3
start end width
[1] 1 20 20
[2] 5 30 26
[3] 30 50 21
[[2]]
IRanges of length 3
start end width
[1] 100 110 11
[2] 200 210 11
[3] 300 310 11
Isn't that what you're after?
