Issues loading packages on a Mac

[adambickford]

A colleague is encountering problems loading several packages on a Mac. Would appreciate any suggestions about how to solve these issues loading tidyverse and tidycensus. rdgal has been installed
The log:

• library(tidyverse) # The tidyverse utilities (including ggplot2)

library(tidycensus) # TidyCensus data access library
Error: package or namespace load failed for ‘tidycensus’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):
there is no package called ‘rgdal’

My colleague is running R Studio 2022.02.3 Build 492 and R 4.2.0
TIA

If library(rgdal) does not work try a reinstall of rgdal. you may have a dodgy install.

install.packages("rgdal")
