Keep only genes with the highest variances

Description

Keep only genes with the highest variances

Usage

filter_by_variance(exp, n = NULL, percentile = NULL)

Arguments

exp	A gene expression data frame with genes in row names and samples in column names or a 'SummarizedExperiment' object.
n	Number of most variable genes (e.g., n=5000 will keep the top 5000 most variable genes).
percentile	Percentile of most highly variable genes (e.g., percentile=0.1 will keep the top 10 percent most variable genes). Values must range from 0 to 1.

Value

Expression data frame or 'SummarizedExperiment' object with the most variable genes in row names and samples in column names.
