[R] How to Dedup a Spatial Points Data Set

I'm new to spatial analysis and am exploring numerous packages, mostly
enjoying sp, gstat, and spBayes.

Is there a function that allows the user to dedup a data set with multiple
values at the same coordinates and replace those duplicated values with the
mean at those coordinates?  I've written some cumbersome code that works,
but would prefer an efficient R function if it exists.  Thanks.
