Thank you Gary for the prompt response!

 

I ran into the following error, which is referenced directly here, and can be found highlighted below:

Error: (converted from warning) package 'lattice' was built under R version 4.0.3

Execution halted

 

If this is an issue on my end, I will address and apologize for another email on the matter.

 

Thank you.

 

Aaron
