Plot EMG Spectral-Fatigue Regression

Source: R/emg-plot.R
plotEmgFatigue.Rd

Scatters the windowed median or mean frequency against time with the fitted fatigue-regression line and slope annotation.

Usage

plotEmgFatigue(
  x,
  feature = c("mdf", "mnf"),
  window_sec = 1,
  overlap = 0.5,
  assay_name = NULL
)

Arguments

x

A PhysioExperiment object with EMG data.

feature

"mdf" (median frequency) or "mnf" (mean frequency).

window_sec, overlap

Windowing passed to emgFatigue().

assay_name

Input assay name (default: first assay).

Value
