In MethReg: Assessing the regulatory potential of DNA methylation regions or sites on gene transcription

Description

Remove genes with gene expression level equal to 0 in a substantial percentage of the samples

Usage

filter_genes_zero_expression(exp, max.samples.percentage = 0.25)

Arguments

exp	Gene expression matrix or SumarizedExperiment object
max.samples.percentage	Max percentage of samples with gene expression as 0, for genes to be selected. If max.samples.percentage 100, remove genes with 0 for 100% samples. If max.samples.percentage 25, remove genes with 0 for more than 25% of the samples.

Value

A subset of the original matrix only with the rows passing the filter threshold.
