calculateSymmetry: Calculate Symmetry (of a Chromatographic Peak)

Description Usage Arguments Details Value Examples

View source: R/calculateSymmetry.R

Description

Calculates the Symmetry of the integrated region of a chromatographic peak. The Symmetry is found by calcuating the correlation between the left and right halves of the peak.

Usage

1
calculateSymmetry(peakData, pts)

Arguments

peakData

A vector containing characteristic information about a chromatographic peak - including the retention time range

pts

A 2D matrix containing the retention time and intensity values of a chromatographic peak
