Check the documentation:

wpg_dp is not one of the allowed object classes.

The link states that the it must be an "object of class sf, sfc or sfg", so you'll have to convert your dataframe.

what would you suggest as a solution? or how would i get around this?

i am trying to map polygon data (i.e., my neighbourhood names) onto the point data.

It worked, thanks!

i figured out my issue: latlong_dp technically isnt a simple feature, by definition a simple feature is an entire row of information along with geometric information
