Plots a heatmap.
Usage
plot_heatmap(object, ...)
# S4 method for matrix
plot_heatmap(object, diag = TRUE, upper = TRUE, lower = TRUE, freq = FALSE)
# S4 method for data.frame
plot_heatmap(object, diag = TRUE, upper = TRUE, lower = TRUE, freq = FALSE)
# S4 method for dist
plot_heatmap(object, diag = FALSE, upper = FALSE, lower = !upper)Arguments
- object

numericmatrixordata.frameof count data (absolute frequencies giving the number of individuals for each class).- ...
Currently not used.
- diag
A
logicalscalar indicating whether the diagonal of the matrix should be plotted. Only used ifobjectis a symmetric matrix.- upper
A
logicalscalar indicating whether the upper triangle of the matrix should be plotted. Only used ifobjectis a symmetric matrix.- lower
A
logicalscalar indicating whether the lower triangle of the matrix should be plotted. Only used ifobjectis a symmetric matrix.- freq
A
logicalscalar indicating whether relative frequency should be used instead of counts (absolute frequency).
