Before applying function, make sure that the CRS of the polygon matches the CRS of the data points.
Each point must belong to only one polygon, otherwise see assign_points_secr.
Returns the original data frame with a new column of the assigned polygon.
IF THERE ARE OVERLAPPING POLYGONS, USE assign_points_secr INSTEAD.
Usage
assign_points_terra(x, y, polygon)
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

Examples
#poly<-get_shapefile('nafo.clipped')
#df2<-assign_points_terra(dat.ziff[1:50,'longitude'],dat.ziff[1:50,'latitude'],poly)
#head(df2)
