Pulse: Calculating Heart Rate

Description

A worker function to calculate heart rate

Usage

pulse.hr(
  signal,
  sampling.rate = 5,
  search.scope = 1,
  score.parameter = 0.5,
  cor.min = 0.5,
  display = c("all", "ppg", "none"),
  ppg.zoom = TRUE
)

Arguments

signal	an integer vector, infrared signal from pulse device.
sampling.rate	an integer, sampling rate in Hz.
search.scope	a numeric, the ratio of lag domain length to the total signal length.
score.parameter	a numeric, the exponent used in the score.
cor.min	a numeric, the correlation threshold for qualified signal.
display	a character string, whether to display plots.
ppg.zoom	a logical, whether to zoom the PPG plot to fit signal intensity.

Value

a mixed list, locmax for local maxima, nominee for the best peak, cor.pass and anticor.pass for quality control, and hr for final heart rate.
