appendZScore: Append zscores to dgeTable

In bedapub/ribiosNGS: Utilities for next-generation sequencing data analysis in ribios

Append zscores to dgeTable

Description

Append zscores to dgeTable

Usage

appendZScore(dgeTable)

Arguments

dgeTable

A data.frame, derived from dgeTables or dgeTable usually. It must contain the following two columns: PValue, and logFC (case sensitive).

Value

A new data.frame with one new column, zScore, containing the z-score transformed from p-values. If that column exists, it will be rewritten. The function is similar to appendPseudoT, with the difference that the Gaussian distribution is used instead of the t-distribution. This solution delivers less extreme values, because t-distribution is heavy-tailed. It allows comparison between studies of different sample sizes.
