WebJun 20, 2024 · Instead of sf objects (= data.frames or tibbles with a geometry list-column), the sp package works with Spatial spatial data classes (which has many derived spatial data classes for points, polygons, …). First, we need to convert the data.frame with point locations to a SpatialPointsDataFrame. The id of each polygon is stored in the ID column of your points_sf_joinded object (the point id is in id column, which may be kind of confusing btw.) See the result of your last plot, slightly amended by me (I have removed the plotting of original coordinates not assigned to a polygon, and color coded the polygon IDs).
