Peak Pseudomoments Symmetry Calculator

Description

This function measures peak symmetry and skewness using the inflection points of the peak on both sides.

Usage

peakPseudomomentsSymmetryCalculator(rt, int)

Arguments

rt

a vector of retention times for the chromatographic peak.

int

a vector of intensities corresponding to the vector of retention times for the chromatographic peak.

Value

PeakSymmetry

peak symmetry for the chromatographic peak.

Skewness

skewness for the chromatographic peak.

Examples

data("peak_spline")
rt <- peak_spline[, 1]
int <- peak_spline[, 2] - peak_spline[, 3]
peakPseudomomentsSymmetryCalculator(rt, int)
