Description Usage Arguments Value Author(s) See Also Examples

View source: R/chicago.R

Description

Finds s_k scaling factors for a (potentially large) number of samples. Typically, these factors are used as library size factors in some sort of differential count algorithm (DESeq, EdgeR, baySeq, ...) to find differential binding events between samples.

Usage

1

Arguments

files

Character vector containing the locations of the .chinput files to read in.

cd

A blank chicagoData object for reference, usually created with setExperiment.
