cpSta: Calculates descriptive statistics

Description

This function calculates descriptive statistics of genes.

Usage

cpSta(expression, ctVal = TRUE)

Arguments

expression

a matrix of expression levels. Each row corresponds to a sample and each column to a gene.

ctVal

a logical value indicating data type. If ct-values are input, ctVal=TRUE, otherwise, ctVal=FALSE.

Value

A matrix of descriptive statistics:

N: number of samples;

GM[CP]: the geometric mean of CP;

AM[CP]: the arithmetic mean of CP;

Min[CP] and Max [CP]: the extreme values of CP;

SD[+/- CP]: the standard deviation of the CP;

CV[CP]: the coefficient of variance expressed as a percentage on the CP level;

Min[x-fold] and Max [x-fold]: the extreme values of expression levels expressed as an absolute x-fold over- or under-regulation coefficient;

SD[+/- x-fold]: standard deviation of the absolute regulation coefficients.
