points: generic method points generic method points

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

Description

Method defining points() for the MassSpectra class points has no generic by default

Usage

points(x, ...)

## S4 method for signature 'MassSpectra'
points(x, y, ..., mzRange = c(0, 200), normalize = FALSE)

Arguments

x	vector with mz for mass spectra plot
...	additional args
y	vector with ion counts for mass spectra plot
mzRange	vector of length 2, indicating the mz range to be plotted
normalize	boolean should the mass spectra be normalized

Details

This function can be used to visualize several spectra in the same plot.

Value

Examples

library(tofsimsData) 
data("tofsimsData")
plot(testImage, type='l', normalize = TRUE, col = 'blue')
points(testSpectra, type = 'l', normalize = TRUE, col = 'red')
