[Bioc-devel] as.list of a GRanges

Hi Bernat,

Use as(gr, "GRangesList") instead of as.list() on your GRanges objects.

Most of the times (e.g. for passing to lapply() or mclapply()), you
don't need an ordinary list, but, if you really want one, you can call
as.list() on the GRangesList object returned by as(gr, "GRangesList").

Hope this helps,
H.

Hi,

I'm having an error in the devel version of my package karyoploteR due to
an error when converting a GRanges into a list of GRanges with "as.list".

This used to be possible and it was working a few weeks ago.

Am I suposed to use a different approach or is there a problem somewhere?

Thanks!

Bernat

Here's an example

rr <- GRanges(seqnames = c("chr1", "chr2"), ranges = IRanges(start=c(1,
2), end=c(11, 12)))
as.list(rr)

And the error message

Error in (function (classes, fdef, mtable)  :
   unable to find an inherited method for function 'getListElement' for
signature '"GRanges"'
