modNormalize: Normalize Data

Description

modNormalize normalizes feature data.

Usage

modNormalize(object, MARGIN = c(1, 2), plotSkip = TRUE)
"modNormalize"(object, MARGIN = c(1, 2), plotSkip = TRUE)

Arguments

object
Specifies the ExprsArray object to undergo pre-processing.
MARGIN
A numeric vector. The margin by which to normalize. Provide MARGIN = 1 to normalize the feature vector. Provide MARGIN = 2 to normalize the subject vector. Provide MARGIN = c(1, 2) to normalize by the subject vector and then by the feature vector.
plotSkip
A logical scalar. Toggles whether to produce side-by-side plots of the before and after ExprsArray summary.

Value

A pre-processed ExprsArray object.

Methods (by class)

  • ExprsArray: Method to normalize an ExprsArray object.

Details

This method normalizes subject and/or feature vectors according to the formula y = (x - mean(x)) / sd(x).
