func_arbGaussian: Calculate Normal Distribution or Gaussian Peak

In pmbrophy/SummitR: Provides a set of tools for peak fitting

Description

Calculates either a normal distribution similar to [dnorm()] with an integrated area of 1 or a gaussian peak with amplitude k

Usage

func_arbGaussian(x, mu, sigma, probDensity, k, weights)

Arguments

x	a vector of x-coordinates from which the corrisponding y-coordinates are calculated
mu	the mean
sigma	the standard deviation
probDensity	Should the function produce a probability density function 'TRUE' or a gaussian peak 'FALSE' with amplitude k? default is 'TRUE'.
k	Amplitude of the peak. Only used when 'probDensity == FALSE'
weights	weighting vector to augment the gaussian shape profile

Value

a vector of y-coordinates the same length as x

Examples

xVec <- seq(from = 1, to = 100, by = 0.1)
weights <- rep(x = 1, times = length(xVec))
weights[490:510] <- 0.1
pdist <- func_arbGaussian(x = xVec, mu = 50, sigma = 1, probDensity = TRUE, weights = weights)
plot(xVec, pdist)
