Hello, 

Does the apply function exist for genomisRange object. Here , I don't talk about a genomicRangesList object but genomic Range.
Is it pertinent to implement it ?

Actually, I populate my gr object with a for loops : depending the position of the gene , I had some information in mcol( gr obj).
unsurprising, the for loop is totally unefficient.
