pairedttestP: paired t-test

In nickytong/GenAnalysis: Genomic Analysis

Description

this calculates paired t test p and other statistics

Usage

pairedttestP(data, class, sampleID = NULL, switchXY = FALSE, minN,
  more = TRUE, levels = NULL, base = 2)

Arguments

data	continuous response vector
class	binary treatment vector
sampleID	a vector of sample ID which can be used to automatically track the paired correspondance.
levels	the user can specify the required ordering c(C1, C2): mean diff is C2-C1.

Details

We need to ensure samples are properly matched for paired data. This bottles down to the binary treatment variable (class) and sample id to track the samples. By default, if sampleID is not specified, it is assumed the samples are correctly matched (the clean case). This actually means class starts with C[1] and then C[2] and no mixture allowed and the sample ID are matched. A more flexible way is to specify class and sampleID simultaneously (in which case class can be mixed) and the code will match class by sampleID through order function. Of course, class and sampleID should have 1-to-1 correspondance.

var.equal has no effect on paired t test;

Value

a vector
