Answer 1

As @jose pointed out in the comments, this can likely be solved by updating your packages. The error you copied is quite long, but the key part appears to be this:

error: function 'Rcpp_precious_remove' not provided by package 'Rcpp'

I am actually the author of choroplethr, and I have no idea what this function is, or why Rcpp is being loaded at all when you load choroplethr. But here we are.

When I paste that error message into DuckDuckGo, the first hit I get is this stackoverflow question.

There the solution appears to simply be typing:

install.packages('Rcpp')
library(Rcpp)

I recommend trying that and seeing if it works.

Regardless of whether that alone solves your problem, I also recommend following the other suggestion @jose made. Namely, typing:

update.packages()

And trying again.

Dependency management in R is a pain. It is probably worth getting into the habit of typing update.packages() when you get an error you don't recognize to see if it magically solves your problem.
