gr.dist: Pairwise distance between two 'GRanges'

In mskilab/gUtils: R Package Providing Additional Capabilities and Speed for GenomicRanges Operations

Pairwise distance between two GRanges

Description

Computes matrix of pairwise distance between elements of two GRanges objects of length n and m.

Distances are computed as follows:

• NA for ranges on different seqnames

• 0 for overlapping ranges

• min(abs(end1-end2), abs(end1-start2), abs(start1-end2), abs(start1-end1),) for all others

If only gr1 is provided, then will return n x n matrix of gr1 vs itself
If max.dist = TRUE, then will replace min with max above

Usage

gr.dist(gr1, gr2 = NULL, ignore.strand = FALSE, ...)

Arguments

gr1	First GRanges
gr2	Second GRanges
ignore.strand	Don't required elements be on same strand to avoid NA [FALSE]
...	Additional arguments to be supplied to GenomicRanges::distance

Value

N by M matrix with the pairwise distances, with gr1 on rows and gr2 on cols
