normSpectra2D {ChemoSpec2D}

Normalize a Spectra2D Object

Description

This function carries out normalization of the spectra in a Spectra2D object. The current options are:

• "zero2one" normalizes each 2D spectrum to a [0 ... 1] scale.

• "minusPlus" normalizes each 2D spectrum to a [-1 ... 1] scale.

• "TotInt" normalizes each 2D spectrum so that the total area is one.

Usage

normSpectra2D(spectra, method = "zero2one")

Arguments

spectra

An object of S3 class Spectra2D to be normalized.

method

Character string giving the method for normalization.

Value

An object of S3 class Spectra2D.

Examples

data(MUD1)
MUD1n <- normSpectra2D(MUD1)
MUD1b <- removeFreq(MUD1, remF2 = 2.5 ~ 3.5)
MUD1bn <- normSpectra2D(MUD1b)
