Hi, I think we should just expand the Rle internally. That will produce a numeric vector of the length of the GRanges i.e. it will be the same size as the start and end components of the GRanges object itself. No big deal at all.
I'll make that change. H. On 04/17/2015 09:00 AM, Michael Lawrence wrote:
Ideally it should be supported, but it would take some work as the coverage stuff is all in C. Could you give more details on your use case? For example, if you already have a range for every position on the chromosome, you could just extract the score column. I'm guessing it's more complicated than that. If the zeros are the problem, you could just subset the GRanges to remove the ranges with zero score, and then coerce the score to numeric before calling coverage.

Especially given the fact that the return value of coverage(x,weight="score") when score is plain numeric vector is always an Rle ! Is this the expected behaviour? If so, I would argue that violates the principle of least suprise :-) The background to this is that I do numerical analysis on derived numerical data along my chromosomes. It contains many contiguous zeroes so it would be wasteful to cast everything down using as.numeric().
