seq_plot

Internal function to convert 'im' object or 'SpatRaster' object to values readable by <code>image.plot</code> function within the <code>plot_perturb</code> function.

Estimates an ecological niche using occurrence data, covariates, and kernel
density-based estimation methods. For a single species with presence and absence data,
the 'envi' package uses the spatial relative risk function that is estimated using the
'sparr' package. Details about the 'sparr' package methods can be found in the tutorial:
Davies et al. (2018) <doi:10.1002/sim.7577>. Details about kernel density estimation can
be found in J. F. Bithell (1990) <doi:10.1002/sim.4780090616>. More information about
relative risk functions using kernel density estimation can be found in J. F. Bithell
(1991) <doi:10.1002/sim.4780101112>.

seq_plot function

<dl><dt>input</dt>
<dd>An object of class 'im' or 'SpatRaster' from the <code>perlrren</code> function.</dd>
<dt>cols</dt>
<dd>Character string of length three (3) specifying the colors for plotting: 1) presence, 2) neither, and 3) absence from the <code>plot_obs</code> function.</dd>
<dt>thresh_up</dt>
<dd>Numeric. The upper value to concatenate the color key. The default (NULL) uses the maximum value from <code>input</code>.</dd>
