bb_import_bw: Import a Big Wig File

In blaserlab/blaseRtools: R Tools for Blaser Lab Data Analysis

Import a Big Wig File

Description

This is a thin wrapper around rtracklayer::import.bw. The purpose is to serve as a helper function for making Trace objects from bigwig files. This function converts the name of the numeric value metadata column to "coverage" for consistency with Trace objects made from Seurat/Signac objects. The numeric column it will look for is "score" by default. This appears to be the default name applied by import.bw and so this is the default value for this function. The option is provided to change it if necessary. The group variable must be supplied. Typically this will be something informative, like "ATAC" or some Histone mark that the data come from.

Usage

bb_import_bw(path, group, coverage_column = "score")

Arguments

path	file path to the bigwig file
group	a label to apply that describes the source data for the track
coverage_column	PARAM_DESCRIPTION, Default: 'score'

Value

a granges object
