5 years ago global library still needs to be installed in order for R to find base packages that are installed with R. It doesn't seem like a good idea to duplicate these packages in the private library, but this also could present a problem if a user wants to install a specific version of a package in the private library when a different version of the package is installed in the global library.

environment(shim_fun) <- shim_env shim_fun(lib_vec)
}
' Set your libPaths to .libPaths()[[1]]
