Plot Pressure Heatmap — pr_plot

Displays a 2D heatmap for a single frame or a summary image (MPP, MVP, PTI, contact frequency).

Usage

pr_plot_heatmap(
  trial,
  frame = NULL,
  type = c("mpp", "mvp", "pti", "contact"),
  show_regions = FALSE,
  palette = "viridis",
  range = NULL,
  interpolate = FALSE,
  title = NULL
)

Arguments

trial: A pr_trial object.
frame: Integer. Frame number to display. If NULL (default), shows the summary picture specified by type.
type: Character. Summary type when frame is NULL: "mpp" (max), "mvp" (mean), "pti" (pressure-time integral), "contact" (contact frequency).
show_regions: Logical. Overlay region boundaries. Default FALSE.
palette: Character. One of "viridis" (default), "inferno", "plasma", "magma", "jet", "classic".
range: Numeric vector of length 2. Colour range. NULL auto-scales.
interpolate: Logical. Reserved for spatial interpolation (currently draws the raw sensor grid). Default FALSE.
title: Character. Plot title. NULL auto-generates.

Value

A ggplot2 object.

Examples

trial <- pr_example_trial("insole")
pr_plot_heatmap(trial)
