Question

I would like to merge/combine two files, so that if an entry in column B of my first file falls into the range of columns B and C in my second file, the output will contain all of the information contained in both files.

Like this:

file 1

     A      B
    rs10    23353
    rs100   10000
    rs234   54440

file 2

    A        B      C
    E235    20000   30000
    E255    50000   60000

where, because 23353 falls between 20000 and 30000, and 54440 falls between 50000 and 60000 the output file would look like this:

rs      23353   E235    20000   30000
rs234   54440   E255    50000   60000

and rs100 would be removed (from the output file) because it does not fall within a range of any row in file 2.

any suggestions?

Thank you!

UPDATE: This question was more complicated than indicated here. The solution can be found here: Merge by Range in R – Applying Loops, and is delivered by using the GenomicRangespackage in Bioconductor. Very useful package!
