Plot lactate thresholds

Plots the result of lactate_threshold(). Without method, an overview: the fitted lactate curve on top and every threshold below, grouped by what the method aims at, on the same intensity axis, with a shaded band for how far the methods aimed at LT1 and at LT2 lie apart, so you can see at a glance how much the methods agree; the two that mark LT1 and LT2 (lt1, lt2, as chosen in lactate_threshold()) are drawn in green. With method, the plot of that one method: what the method fitted, the measured stages, and the threshold with its intensity, lactate and heart rate.

Usage

# S3 method for class 'lactate_thresholds'
autoplot(object, method = NULL, lt1 = NULL, lt2 = NULL, ...)

# S3 method for class 'lactate_thresholds'
plot(x, method = NULL, ...)

Arguments

object, x

The result of lactate_threshold().

method

A method to plot (one of object$method), or NULL for the overview.

lt1, lt2

The thresholds that mark LT1 and LT2, drawn in green in the overview. Default to those chosen in lactate_threshold().

...

Not used.

Value

a ggplot2 (one method) or patchwork (overview) object.

Details

The plots are ggplot2 objects: add layers, scales or a theme() to change them. See theme_lactater() for the dark style (options(lactater.style = "night")) and the font.

Examples

results <- lactate_threshold(
  demo_data,
  intensity_column = "intensity",
  lactate_column = "lactate",
  heart_rate_column = "heart_rate",
  plot = FALSE
)
autoplot(results)

autoplot(results, method = "Dmax")
