sdm_spec_maxent

This function returns a <a href="https://parsnip.tidymodels.org/reference/model_spec.html">parsnip::model_spec</a> for a MaxEnt model to be used
in Species Distribution Models.

Fit species distribution models (SDMs) using the 'tidymodels' framework,
which provides a standardised interface to define models and process their
outputs. 'tidysdm' expands 'tidymodels' by providing methods for spatial objects,
models and metrics specific to SDMs,
as well as a number of specialised functions to process occurrences
for contemporary and palaeo datasets. The full
functionalities of the package are described
in Leonardi et al. (2023) <doi:10.1101/2023.07.24.550358>.
