generatePseudoGaussianSpectrum: Generate the points from a pseudo Gaussian Spectrum.

In Yang0014/glycoNativeMS: Glyco Native Mass Spectrometry Analysis

Description

Given the locations and intensities of peaks, generate the data points of pseudo gaussian spectrum.

Usage

generatePseudoGaussianSpectrum(x, y, sd, xlim = range(x))

Arguments

x	A numric vector: the locations of the peaks.
y	A numeric vector: the intensities of the peaks.
sd	A numeric value: the standard deviation of the pseodo gaussian distribution. It controls the wideness of the distribution.
xlim	The desired range of simulated data points.

Value

A data.frame of coordinates and intensities.

set.seed(1)
## The x-coordinates of peaks
x <- c(100, 200, 350, 400, 550, 600, 800)
## The intensities of peaks
y <- sample(1:100, size=length(x))
## Generate the points of pseudo gaussian spectrum of peaks
ans <- generatePseudoGaussianSpectrum(x, y, sd=5, xlim=c(1,1000))
## Plot the pseudo gaussian spectrum
plot(ans$x, ans$y, type="l")
