fread.bed {ORFik} | R Documentation

## Load bed file as GRanges

### Description

Wraps around `import.bed` and tries to speed up loading with the use of data.table. Supports gzip, gz, bgz and bed formats. Also safer chromosome naming with the argument chrStyle

### Usage

    fread.bed(filePath, chrStyle = NULL)

### Arguments

`filePath` | The location of the bed file
`chrStyle` | a GRanges object, TxDb, FaFile, or a `seqlevelsStyle` (Default: NULL) to get seqlevelsStyle from. Is chromosome 1 called chr1 or 1, is mitocondrial chromosome called MT or chrM etc. Will use 1st seqlevel-style if more are present. Like: c("NCBI", "UCSC") -> pick "NCBI"

### Value

a `GRanges` object

                            package = "ORFik")
    fread.bed(cageData)
