In meysubb/cfbscrapR: A Scraping and Aggregating Interface to the CollegeFootballData API

cfbscrapR 1.0.22

• ~~Fix conference parameters to match API (moved to abbreviation format).~~ Removed assertions for now, so users should be able to access conference data without issue, assuming the input argument is correct. May fortune favor your selection.

• Add mgcv (>= v1.8.32) dependency and update WP model accordingly. Note on WPA: Kickoffs are problematic and our calculation algorithm does not appear to accomplishing what it needs to. We are working on this, aiming for a quick next version update centered around this.

• Following play type renamings and merging:

• Pass Interception Return --> Interception Return
• Pass Interception --> Interception Return
• Pass Interception Return Touchdown --> Interception Return Touchdown
• Sack Touchdown --> Fumble Recovery (Opponent) Touchdown

• Punt Touchdown ~ Punt Return Touchdown.

• Update rush_vec and pass_vec regex definitions to be more precise on pulling rushing plays.

• Update definition of play_type definition for cleaning "Fumble Recovery (Opponent)" play types to actually distinguish between touchdowns and non-scoring opponent fumble recoveries (prior definition was combining the touchdowns into the non-scoring play type)

• Reduce the reach of the non-explicit rushing/passing touchdowns to be more careful about merging labels.

• Similarly, separated punt touchdowns into a specific type of offensive score where the punting team recovers a fumble and scores, all other punt touchdowns prior to this were punt return touchdowns. There is a specific Jalen Reagor (TCU) play where he pulls a Greg Reid and fumbles on the punt return only to recover the fumble and run it in for a 73 yard TD that is explicitly fixed.

• Add the following columns:

• kickoff_onside
• kickoff_fair_catch
• kickoff_downed
• punt_fair_catch
• punt_downed
• sack
• int
• int_td
• completion
• pass_attempt
• target
• pass_td
• rush_td

• safety

• add some return skeleton docs

• add column drive_start_yardline to the remove cols

• add parsing for kickoff safeties accounting for sign change

• Added Jared Lee's animated win probability plot vignette to the package documentation page

• Contains important add_player_cols() function useful to parse existing play-by-play datasets and pull passer/rusher/receiver/etc. player names.
• Added Michael Egle's 4th down tendency plot vignette to the package documentation page

cfbscrapR 1.0.21

• Fix conference parameters to match API (moved to abbreviation format).

cfbscrapR 1.0.2

• Fix downs turnovers and several other discrepancies in EPA computations.

• Fix majority of issues with win probability added.

• Remove the add_betting_columns() function and the current betting win probability model from the cfb_pbp_data() function.
• Added cfb_ratings_fpi() function from @sabinanalytics's fork of the repository
• Added the cfb_metrics_espn_wp() function, courtesy of @mrcaseb
• Add tests for a majority of the functions. This is the biggest behind the scenes change that will translate to more reliable functions.
• Rename several function outputs from camelCase to under_score for consistency. Please adjust your scripts accordingly, apologies for the inconvenience.
• Remove drives parameter from cfb_pbp_data() function. For accessing drives information, please switch to the cfb_drives() function.
