Title Use EIC data to do peak detection and calculate entropy of each peaks within a retention time range.

Description

Title Use EIC data to do peak detection and calculate entropy of each peaks within a retention time range.

Usage

peakDectAndEntroCal(eicData, trRange, m = 200)

Arguments

eicData,	a matrix containing EIC data, the first column is rt (retention time) and the second column is intensity.
trRange	retention time range for extraction.
m	parameter of peak detection.

Value

extractedPeaks
