This function forces points of an object of class
[
sf] located outside
the limits defined by an object of class sp::SpatialPolygons
to NA
.
st_filter_prevR(x, y)
Return x
filtered by y
The function try to apply sf::st_filter()
. In case it fails,
it will try to rebuild y
according to spherical geometry
(see sf::st_as_s2()
) before filtering. If it still fail, it will return
x
unfiltered.
