Quantile Normalization

This function normalises the input data via quantile normalisation technique.

Usage

quantileNormalization(
  x,
  na.rm = TRUE,
  ties.method = c("min", "max", "first", "last")
)

Arguments

x

numerical matrix, features-by-samples

ties.method

a character string specifying how ties are treated, see ‘Details’; can be abbreviated.

Value

A numerical matrix containing the normalized values.
