Points in Polygons Data Function error warnings

Im trying to run a data function in my Spotfire project, but an encountering some errors.

https://community.tibco.com/modules/points-polygons-data-function-tibco-...

 

When I try to run the data function in the sample DXP I get the following warning message:

Loading required namespace: rgdal

 

When I try to run the data function in my own data I get the following warning message:

I have the "sp", "wkb", and "rgdal" packages installed.

Any ideas why I am getting these warning messages?
