GenomicRanges (version 1.18.4)

tile-methods: Tile a GenomicRanges object

Description

tile method for GenomicRanges. Partitions the each range into a set of tiles. Tiles are defined in terms of their number or width.

Usage

"tile"(x, n, width)

Arguments

x

A GenomicRanges object, like a GRanges.

n

The number of tiles to generate. See ?tile in the IRanges package for more information about this argument.

width

The (maximum) width of each tile. See ?tile in the IRanges package for more information about this argument.

Value

A GRangesList object, each element of which corresponds to a tile.

Examples

gr <- GRanges(
        seqnames=Rle(c("chr1", "chr2", "chr1", "chr3"), c(1, 3, 2, 4)),
        ranges=IRanges(1:10, end=11),
        strand=Rle(strand(c("-", "+", "*", "+", "-")), c(1, 2, 2, 3, 2)),
        seqlengths=c(chr1=11, chr2=12, chr3=13))

# split every range in half
tiles <- tile(gr, n = 2L)
stopifnot(all(elementLengths(tiles) == 2L))

# split ranges into subranges of width 2
# odd width ranges must contain one subrange of width 1
tiles <- tile(gr, width = 2L)
stopifnot(all(all(width(tiles) %in% c(1L, 2L))))
