map_bed  R Documentation 
Map overlapping features in data
onto intervals in scaffold
and apply
statistics and/or summary operations on those features.
map_bed( x, y, operation, max_gap = 1L, min_overlap = 0L, min_overlap_type = c("bp", "frac1", "frac2") )
x 
A 
y 
A 
operation 
List of functions for the statistics and summary operations.
This is similar to 
max_gap 
The largest gap for two intervals to be considered as overlapping. Default is 1 (no gap allowed, adjacent intervals not allowd). 
min_overlap 
See 
min_overlap_type 

A mapped GRanges
object.
