cfbfastR
The goal of cfbfastR
is to provide the community with an R package for working with CFB data. It is an R API wrapper around https://collegefootballdata.com/. Beyond data aggregation and tidying ease, one of the multitude of services that cfbfastR
provides is for benchmarking open-source expected points and win probability metrics.

Breaking Changes
College Football Data API Keys
The CollegeFootballData API now requires an API key, here’s a quick run-down:
To get an API key, follow the directions here: College Football Data Key Registration.
Using the key: You can save the key for consistent usage by adding
CFBD_API_KEY=YOUR-API-KEY-HERE
to your .Renviron file (easily accessed viausethis::edit_r_environ()
). Runusethis::edit_r_environ()
, a new script will pop open named.Renviron
, THEN paste the following in the new script that pops up (without quotations)
CFBD_API_KEY = YOUR-API-KEY-HERE
Save the script and restart your RStudio session, by clicking Session
(in between Plots
and Build
) and click Restart R
(there also exists the shortcut Ctrl + Shift + F10
to restart your session). If set correctly, from then on you should be able to use any of the cfbd_
functions without any other changes.
- For less consistent usage: At the beginning of every session or within an R environment, save your API key as the environment variable
CFBD_API_KEY
(with quotations) using a command like the following.
Sys.setenv(CFBD_API_KEY = "YOUR-API-KEY-HERE")
