Plots a spot matrix.
plot_spot(object, ...)# S4 method for matrix
plot_spot(object, threshold = NULL, diag = TRUE, upper = TRUE, ...)
# S4 method for dist
plot_spot(object, diag = FALSE, upper = FALSE, ...)
# S4 method for OccurrenceMatrix
plot_spot(object, diag = FALSE, upper = FALSE, ...)
An abundance matrix to be plotted.
Extra parameters to be passed to threshold.
A function that takes a numeric vector as argument and
returns a numeric threshold value. If NULL (the default), no threshold is
computed.
A logical scalar indicating whether the diagonal of the
matrix should be plotted.
A logical scalar indicating whether the upper triangle of
the matrix should be plotted.
A ggplot2::ggplot object.
The spot matrix can be considered as a variant of the Bertin diagram where the data are first transformed to relative frequencies.

plot_diversity,
