WebDescription This function finds all peaks (local maxima) in a spectrum, using a user provided size threshold relative to the tallest peak (global maximum) bellow which found peaks are ignored---i.e., not included in the returned value. This is a wrapper built on top of function peaks () from package 'splus2R'. Usage WebThe peak is always placed in the middle of the window therefore the given length is rounded up to the next odd integer. This parameter can speed up the calculation (see Notes). Returns: prominencesndarray The calculated prominences for each peak in peaks. left_bases, right_basesndarray
