Plot a stage-transition heatmap — plot_transition_matrix • hypnoR

Renders the transition probability (or count) matrix returned by compute_transitions() as a heatmap using ggplot2.

Usage

plot_transition_matrix(
  transitions,
  label_values = TRUE,
  digits = 2L,
  title = NULL
)

Arguments

transitions: The matrix element of the list returned by compute_transitions(): a tibble with a from column plus one numeric column per to stage.
label_values: If TRUE (default), cell values are printed inside each tile. NA cells (unvisited from-stages) are left blank.
digits: Number of decimal places for cell labels. Default 2.
title: Optional plot title.

Value

A ggplot object.

Examples

if (FALSE) { # \dontrun{
hyp   <- read_hypnogram("night_001.csv")
trans <- compute_transitions(hyp)
plot_transition_matrix(trans$matrix)
} # }
