Before applying function, make sure that the CRS of the polygon matches the CRS of the data points.
Returns a dataframe. There is a column for each polygon with 1 or 0 indicating
whether each point falls within the polygon. There is also a column to indicate which polygon(s) each
point has been assigned to. USE THIS INSTEAD OF assign_points_terra WHEN THERE ARE OVERLAPPING POLYGONS.
Usage
assign_points_secr(x, y, polygon, polygon.label)
Arguments
- x
X coordinate (e.g., longitude) with same CRS as polygon
- y
Y coordinate (e.g., latitude) with same CRS as polygon
- polygon
Spatvector with geometry polygons
- polygon.label
The layer containing the name of each polygon in the Spatvector
Value
Returns a dataframe with nrow = df. There is a column for each polygon with 1 or 0 indicating
whether each point falls within the polygon. There is also a column to indicate which polygon(s) each
point has been assigned to.
