I'm trying to use the county_choroplethr function of library(choropleth) package in R. I have installed, uninstalled, and re-installed this package repeatedly, but keep getting:
Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) : there is no package called ‘tibble’
In addition:
Warning messages: 1: package ‘choroplethr’ was built under R version 3.2.5 2: package ‘stringr’ was built under R version 3.2.5 3: package ‘XML’ was built under R version 3.2.5 Error: package or namespace load failed for ‘choroplethr’
