Prepare an 'im' or 'SpatRaster' object for plotting with diverging color palette

Description

Internal function to convert 'im' object or 'SpatRaster' object to values readable by image.plot function within the plot_obs, plot_predict, and plot_perturb functions.

Usage

div_plot(
  input,
  cols,
  midpoint = 0,
  thresh_up = NULL,
  thresh_low = NULL,
  digits = 1
)

Arguments

input	An object of class 'im' or 'SpatRaster' from the lrren function.
midpoint	Numeric. The value to center the diverging color palette.
thresh_up	Numeric. The upper value to concatenate the color key. The default (NULL) uses the maximum value from input.
thresh_low	Numeric. The lower value to concatenate the color key. The default (NULL) uses the minimum value from input.
digits	Integer. The number of significant digits for the labels using the round function (default is 1).
plot_cols	Character string of length three (3) specifying the colors for plotting: 1) presence, 2) neither, and 3) absence from the plot_obs function.

Value

An object of class 'list'. This is a named list with the following components:

v

An object of class 'vector' for the estimated ecological niche values.

cols

An object of class 'vector', returns diverging color palette values.

breaks

An object of class 'vector', returns diverging color palette breaks.

at

An object of class 'vector', returns legend breaks.

labels

An object of class 'vector', returns legend labels.
