Finding overlap in ranges with R

Question

I have two data.frames each with three columns: chrom, start & stop, let\'s call them rangesA and rangesB. For each row of rangesA, I\'m looking to find which (if any)

Answer 1

I add the dplyr solution.

library(dplyr)
inner_join(rangesA, rangesB, by="chrom") %>% 
  filter(start.y < start.x | stop.y > stop.x)

Output:

  chrom start.x stop.x start.y stop.y
1     5     100    105      99    106
2     1     200    250     200    265
