grid_offset

This function facilitates using spatialsample::spatial_block_cv multiple
times in an analysis. spatialsample::spatial_block_cv creates a grid based
on the object in <code>data</code>. However, if spatial blocks are generated multiple
times in an analysis (e.g. for a <code>spatial_initial_split()</code>, and then
subsequently for cross-validation on the training dataset), it might be
desirable to keep the same grid). By applying this function to the largest
dataset, usually the full dataset before <code>spatial_initial_split()</code>. The
resulting cellsize can be used as an option in
spatialsample::spatial_block_cv.

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>.
