tile1 {ORFik} | R Documentation

## Tile each GRangesList group to 1-base resolution.

### Description

Will tile a GRangesList into single bp resolution, each group of the list will be splited by positions of 1. Returned values are sorted as the same groups as the original GRangesList, except they are in bp resolutions. This is not supported originally by GenomicRanges for GRangesList.

### Usage

    tile1(grl, sort.on.return = TRUE, matchNaming = TRUE, is.sorted = TRUE)

### Arguments

`grl` | a `GRangesList` object with names.
`sort.on.return` | logical (TRUE), should the groups be sorted before return (Negative ranges should be in decreasing order). Makes it a bit slower, but much safer for downstream analysis.
`matchNaming` | logical (TRUE), should groups keep unlisted names and meta data.(This make the list very big, for > 100K groups)
`is.sorted` | logical (TRUE), grl is presorted (negative coordinates are decreasing). Set to FALSE if they are not, else output will most likely be wrong!

### Value

a GRangesList grouped by original group, tiled to 1

### Examples

    gr1 <- GRanges("1", ranges = IRanges(start = c(1, 10, 20),
                                         end = c(5, 15, 25)),
                   strand = "+")
    gr2 <- GRanges("1", ranges = IRanges(start = c(20, 30, 40),
                                         end = c(25, 35, 45)),
                   strand = "+")
    names(gr1) = rep("tx1_1", 3)
    names(gr2) = rep("tx1_2", 3)
    grl <- GRangesList(tx1_1 = gr1, tx1_2 = gr2)
    tile1(grl)
