Peak Derivative Skewness Calculator

Description

This function calculates skewness of a chromatographic peak using first order degree of numerical differentiation.

Usage

peakDerivativeSkewnessCalculator(rt, int)

Arguments

rt

a vector representing retention times of the chromatographic peak.

int

a vector representing intensities of the chromatographic peak.

Value

Skewness of a chromatographic peak. 1 is for very symmetric peak. Minimum is 0 from this function.

Examples

data(peak_spline)
rt <- peak_spline[, 1]
int <- peak_spline[, 2]
