arle {mimager} | R Documentation |
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.
arle(x, log2 = TRUE, normalize = TRUE)
x |
a three-dimensional |
log2 |
should values be $log_2$ transformed |
normalize |
should values be quantile normalized |
an array
with the same dimensions as x
