rntransform: rank normal tranformation

In MRCIEU/metaboprep: Metabolomics data preparation and processing pipeline

rank normal tranformation

Description

This function rank normal transforms a vector of data. The procedure is built off of that provided in the GenABEL pacakge.

Usage

rntransform(y, split_ties = TRUE)

Arguments

y	a numeric vector which will be rank normal transformed
split_ties	a binary string of TRUE (default) or FALSE indicating if tied values, of the same rank, should be randomly split giving them unique ranks.

Value

returns a numeric vector, with the same length as y, of rank normal transformed values

Examples

## simulate a negative binomial distribution of values
nb_data = rnbinom(500, mu = 40, size = 100)
## rank normal transform those values
rnt_data = rntransform( nb_data , split_ties = TRUE )
