Time to peak torque

Time to peak torque

Usage

timeToPeakTorque(
  torque,
  sampling_rate,
  onset = NULL,
  onset_method = c("absolute", "sd"),
  onset_threshold = 7.5,
  baseline_ms = 100,
  baseline_sd_k = 5
)

Arguments

torque

Numeric torque trace in N m.

sampling_rate

Sampling rate in Hz.

onset

Optional 1-based integer onset sample. When NULL, onset is detected from the baseline.

onset_method

Either a fixed "absolute" increase above baseline or a baseline "sd" rule.

onset_threshold

Absolute onset threshold in N m above baseline.

baseline_ms

Baseline duration in milliseconds.

baseline_sd_k

Number of baseline SDs used by the "sd" method.

Value

A named list containing time from onset, time from trace start, peak and onset indices, and peak torque.

Examples

torque <- c(rep(0, 100), seq(0.4, 120, by = 0.4), rep(120, 100))
timeToPeakTorque(torque, sampling_rate = 1000, onset_method = "sd")
