test.group.shuffle: Function to do compute test statistic iterativelly

In MAMA: Meta-Analysis of MicroArray

Description

Function computes test statistic with random assignment of group labels to samples in each iteration. It binds results to one matrix. Finaly it multiplies values of test statistics by -1. It saves a file necessary in MAP-Matches method.

Usage

test.group.shuffle(x,  varname, minSampleNum = 3, method = "t",B=1000)

Arguments

x	MetaArray object
varname	String indicating the column of clinical data matrices definig groups
minSampleNum	Minimal number of samples required for test statistic
method	Type of test as in mt.teststat
B	Number of iterations

Value

matrix of test statistics (with random group assignment and multiplied by -1)
