scale: generic for scale

In tofsims: Import, process and analysis of Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS) imaging data

Description

scale autoscaling method for MassSpectra object. Scaling is along the mass channels. Therefore more than one spectra is needed for scaling.

Usage

scale(x, center = TRUE, scale = TRUE)

## S4 method for signature 'MassSpectra'
scale(x, center = TRUE, scale = TRUE)

Arguments

x	object object of class MassSpectra
center	boolean should data be centered
scale	boolean should data be scaled

Value

object of class MassSpectra with scaled mass spectra

object of class MassSpectra

Examples

## autoscaling of dummy image data
testImage<-MassImage('dummy')
par(mfcol=c(2,2))
plot(testImage,type='l')
image(testImage)
testImage <- scale(testImage)
plot(testImage,type='l')
image(testImage)
## Not run: 
## autoscaling of real spectral data
library(tofsimsData)
data(tofsimsData)
par(mfcol=c(2,2))
plot(testImage,type='l')
image(testImage)
testImage <- scale(testImage)
plot(testImage,type='l')
image(testImage)
## End(Not run)
