crosscoverage-methods: Retrieve the cross coverage values for a range of shift sizes

In genialis/ChIPQC: Quality metrics for ChIPseq data

Retrieve the cross coverage values for a range of shift sizes

Description

Retrieves the cross-coverage values for a range of shift sizes.

Methods

signature(object = "ChIPQCexperiment")

Retrieve a matrix of cross-coverage data for all samples in an ChIP-seq experiment. Each column represents a sample, and each row a shift size, with the value representing the cross-coverage using that size read.

signature(object = "list")

Retrieve a matrix of cross-coverage data for all samples in a list of ChIPQCsample objects. Each column represents a sample, and each row a shift size, with the value representing the cross-coverage using that size read.

signature(object = "ChIPQCsample")

Retrieve a vector of cross-coverage data for a sample. Each position in the vector corresponds to a shift size, with the value representing the cross-coverage using that size read.

     xlab="Fragment length") 

allcoverages = crosscoverage(exampleExp)
dim(allcoverages)
