Tools to utilize Census Transportation Planning Package (CTPP) data for geographies in the Central Puget Sound Region.
Install with the following command: devtools::install_github("psrc/psrcctpp")
If you are having problems installing the package, make sure you have all the latest dependency packages. You may be prompted to install some dependency packages after that; you can install all by selecting option 1, "Install all".
This package requires a valid CTPP API key; to obtain one, visit https://ctppdata.transportation.dev/ -> Login -> Create an account. Once successfully logged in the options associated with your account (at top right of screen, hover username) include "Manage API Keys". Create a key there, then make an .renviron entry named CTPP_API_KEY with this value, in single quotes (the command usethis::edit_r_environ() conveniently locates and opens the file for you).
