getBackgroundFrequencies {PWMEnrich}R Documentation

Get the four nucleotides background frequencies

Description

Estimate the background frequencies of A,C,G,T on a set of promoters from an organism

Usage

getBackgroundFrequencies(organism = "dm3", pseudo.count = 1, quick = FALSE)

Arguments

organism

either a name of the organisms for which the background should be compiled (supported names are "dm3", "mm9" and "hg19"), a BSgenome object, DNAStringSet, or list of DNAString objects

pseudo.count

the number to which the frequencies sum up to, by default 1

quick

if to preform fitting on a reduced set of 100 promoters. This will not give as good results but is much quicker than fitting to all the promoters (~10k). Usage of this parameter is recommended only for testing and rough estimates.
