I have two sf multipolygon layers - one is a 5km buffer along the Mexico-US border and the other is an administrative 2-level layer of Mexico. I am trying to figure out how to layer these on top of one another and have the final product be one layer that can be visualized like this:
I have tried spatially joining with
st_join, however this results in either just the border polygon with attributes from the admin 2 layer (listing buffer layer first) or in the admin 2 layer with buffer layer attributes. I am looking to get one layer with the polygons from both and attributes in overlapping areas to be defined by the buffer layer.
