pts |
A SpatialPolygons* object. |
tabulate |
Logical. If |
min_n |
The minimum number of points a region must contain in order for
the region name to be returned when |

Character. Either |
If tabulate
is FALSE
, a vector of IBRA 7 subregion (or
region, see type
) names corresponding to the IBRA 7 regions (or
subregions) that at least min_n
pts
fall within. If
tabulate
is TRUE
, a named vector showing the number of points
in each occupied IBRA 7 subregions (or regions). Points that do not overlie
an IBRA 7 subregion will be ignored with a warning.
