plyranges – joining gpos object only by the start coordinate of the range

Question

[Kateřina]

Hi,

I am using plyranges for joins. I can't figure out how to join a GPos object with GRanges object by start position. The idea is that I want to join rows, where position in GPos object is equal to the starting coordinate in GRanges object. The within version of the funciton won't help, because there could be multiple positions found within the ranges (unlike the unique starting one). Is there any way to do it and use join_overlap_left_directed(GPos, GRanges) with some parameters?

Thank you in advance
