extentToVect

This function returns a <code>SpatVector</code> or <code>sf</code> polygon representing an extent. The input can be a <code>SpatExtent</code> or <code>sf</code> object, or an object from which a <code>SpatExtent</code> (extent) can be obtained.

Implements species distribution modeling and ecological niche
modeling, including: bias correction, spatial cross-validation, model
evaluation, raster interpolation, biotic "velocity" (speed and
direction of movement of a "mass" represented by a raster), interpolating
across a time series of rasters, and use of spatially imprecise records.
The heart of the package is a set of "training" functions which
automatically optimize model complexity based number of available
occurrences. These algorithms include MaxEnt, MaxNet, boosted regression
trees/gradient boosting machines, generalized additive models,
generalized linear models, natural splines, and random forests. To enhance
interoperability with other modeling packages, no new classes are created.
The package works with 'PROJ6' geodetic objects and coordinate reference
systems.

<dl><dt>x</dt>
<dd>A <code>sf</code>, <code>SpatVector</code>, <code>SpatRaster</code>, <code>sf</code>, or a vector of four numeric values representing (in this order): x-coordinate of western side of the extent, x-coordinate of eastern side, y-coordinate of the southern side, and y-coordinate of the northern side. If numeric coordinates are supplied, the output will not have a CRS assigned to it unless supplied in <code>...</code></dd>
