cfbfastR v1.6.5

• Updated tests and documentation for cfbd_betting_lines()

cfbfastR v1.6.1

• Removed source urls from many package documentation entries.
• Updated a test to skip on CRAN

cfbfastR v1.6.0

• Added cfbd_ratings_elo() function

• Remove verbose parameter

cfbfastR v1.5.1

Minor release

• Removed calculated columns from cfbd_stats_season_team() that were not behaving correctly

Add support for parallel processing and progress updates

• Added furrr, future, and progressr dependencies to the package to allow for parallel processing of the play-by-play data with progress updates if desired.

cfbfastR v1.0.0

Function Naming Convention Change

• All functions sourced from the College Football Data API will start with cfbd_ as opposed to cfb_ (as in cfbscrapR). One additional cfbd_ function has been added that corresponds to the result when cfbd_pbp_data() has the parameter epa_wpa=FALSE. It has now been separated into its own function for clarity cfbd_plays(). The parameter and functionality still exists in cfbd_pbp_data() but we expect this function will still exist but made obsolete in favor of a function more closely matching nflfastR's naming conventions.

• Similarly, data and metrics sourced from ESPN will begin with espn_ as opposed to cfb_. In particular, the two functions are now espn_ratings_fpi() and espn_metrics_wp()

• Data generated from any of the cfbfastR methods will use cfb_

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=XXXX-YOUR-API-KEY-HERE-XXXXX to your .Renviron file (easily accessed via usethis::edit_r_environ()). Run usethis::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 = XXXX-YOUR-API-KEY-HERE-XXXXX

Save the script and restart your RStudio session, by clicking Session (in between Plots and Build) and click Restart R (n.b. 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 = "XXXX-YOUR-API-KEY-HERE-XXXXX")

• Added API Key methods. If you forget to set your environment variable, functions will give you a warning and ask for one.
