rank.based.INT: Rank-based Inverse Normal Transformation

In lixiangchun/lxctk: Li Xiangchun's tool-kit (lxctk)

Description

Transfrom input vector with Rank-based Inverse Normal Transformation.

Usage

rank.based.INT(x, c=3/8)

Arguments

x	vector of inputs to be transformed.
c	hyper-parameter can be used to control INT: Blom (c=3/8), Tukey (c=1/3), Rankit (c=1/2) and van der Waerden (c=0).

Examples

data(SLC12A7_tumor_expression)
y <- rank.based.INT(SLC12A7_tumor_expression)

## for comparison
plot(density(SLC12A7_tumor_expression), xlab='SLC12A7 mRNA level', main='Density plot of raw data')

plot(density(y), xlab='SLC12A7 mRNA level', main='Density plot of INT data')
