|
spdf_object |
SpatialPolygonsDataFrame representing species' geographic distributions. The data.frame associated with the object must contain a column named "Species" to distinguish among features. |
spdf_grid |
geographic grid for the region of interest (output of
function |
parallel |
(logical) whether to perform analyses in parallel. Default = FALSE. |
n_cores |
(numeric) number of cores to be used when |
A data.frame of species' found in distinct positions (defined with identifiers); includes two columns: "ID" and "Species".
