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.

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

`x`	a three-dimensional `array` of matrices
`log2`	should values be $log_2$ transformed
`normalize`	should values be quantile normalized

an array with the same dimensions as x
