Description

This function finds the indices of all peaks in the given signal vector. A peak is taken to occur whenever a rising part in the signal is followed by a falling part.

Usage

FindAllPeaks(inSignal, inFlatPreference = "center")

Arguments

inSignal	the signal that is scanned for peaks (a numeric vector).
inFlatPreference	preference for choosing exact position in case of flat peaks: if "left", the leftmost point of a flat peak is chosen if "center", the center of a flat peak is chosen if "right", the rightmost point of a flat peak is chosen. If empty or not specified, "center" is used by default.

Value

A numeric vector with the indices of the peaks (could be empty!).
