diast_pk: diast_pk

In stw32/PulseWaveform: Extraction of Photoplethysmography Waveform Features and Decomposition Modeling of Pulse Waveforms

diast_pk

Description

diast_pk finds the position of the diastolic peak (D) on the average wave so as to inform identification of OSND points on all individual waveforms. Since the average waveform being evaluated is also free from NA values, the resultant shift along the x-axis in terms of index points is also calculated.

Usage

diast_pk(avw, sr, scale = F, dias_param = NULL)

Arguments

avw	average waveform
sr	sampling rate
scale	logical - to establish bounds of y-axis
dias_param	optional - to inform search for D if the waveform is a HED modelled one

Value

diastPk	diastolic peak position on the average waveform
xShift	difference in x-axis values of the average waveform due to removal of NA values

Examples

tmp <- diast_pk(avw = avWave, sr = samplingRate, scale = T)
