arle {mimager}R Documentation

Array relative log expression

Description

The relative log expression (RLE) quantifies the extent to which each sample in a dataset differs from a "reference" sample, which represents each probe's median value across all samples.

Usage

arle(x, log2 = TRUE, normalize = TRUE)

Arguments

x

a three-dimensional array of matrices

log2

should values be $log_2$ transformed

normalize

should values be quantile normalized

Value

an array with the same dimensions as x
