METRADISC: Wrapper function for METRADISC method

Description

This is a wrapper function for meta-analytical method called METRADISC that perform all steps of the analysis and return all the outputs in one line.

Usage

METRADISC(data, varname, nperm = 1000)

Arguments

data
MetaArray object
varname
Character String - name of one column in clinical data matrices to be used as class labels
nperm
Number of permutations for Monte Carlo permutation test, at least 1000 is suggested

Value

An object of class METRADISC.res containing
ranks
Ranks of the genes in each dataset
RQ
Average rank (R) and measure of heterogeneity (Q) for each gene
MCtest
Four p-values (for low and high R and low and high Q) for each gene as provided after Monte Carlo permutation test
