permutePLSDA: permutePLSDA

In metaX: An R package for metabolomic data analysis

Description

Validation of the PLS-DA model by using permutation test statistics

Usage

permutePLSDA(x, y, n = 100, np = 2, outdir = "./", prefix = "metaX",
  tol = 0.001, cpu = 0, ...)

Arguments

x	a matrix of observations.
y	a vector or matrix of responses.
n	number of permutations to compute the PLD-DA p-value based on R2 magnitude. Default n=100
np	the number of components to be used in the modelling.
outdir	output dir
prefix	the prefix of output figure file
tol	tolerance value based on maximum change of cumulative R-squared coefficient for each additional PLS component. Default tol=0.001
cpu	0
...	additional arguments

Value

pvalue
