Introduction to toRvik

Hey everyone, I’m Andrew Weatherman, the developer and maintainer of toRvik. I created toRvik to solve one distinct problem facing men’s college basketball: A lack of accessible open-source data. Synergy, CBB Analytics, and KenPom are great analytics solutions, but they are neither open source nor free. toRvik offers speedy access to some of the most extensive and detailed college basketball data on the planet – for free and with just a few lines of code!

What to expect

toRvik offers in-depth access to player, team, and coaching data, with most statistics back-logged to the 2007-2008 season. Granular data is available for game-by-game player statistics, offering over 40 variables per player, unprecedented access to transfer and recruiting histories, and an industry-leading game predictor model created by Bart Torvik.

Install R and RStudio

To get started, you’ll need to have R and, preferably, RStudio installed on your machine.

  1. Head to

  2. Select the appropriate link for your operating system (Windows, Mac OS X, or Linux)

  1. Head to
  2. Follow the associated download and installation instructions for RStudio.
  3. For Windows users: I recommend installing RTools. Many R packages will require it to successfully compile. Assuming you have downloaded the latest version of R, similarly download the latest version of RTools.

Install toRvik

The released CRAN version can be downloaded using the following:


Whereas the latest development version can be downloaded using:

if (!requireNamespace('devtools', quietly = TRUE)){

Once you have R, RStudio, and toRvik installed, you are ready to start digging through the data!

Function structures

toRvik offers functions that cover five major categories: Rating, player, team, game, and tournament.


toRvik pulls current and archived ratings from T-Rank, a well-respected leader in college basketball analytics. Historical ratings are available back to the 2014-15 season and can be aggregated by date, team, or year. Both rating functions return current and projected team records, barthag – the projected win percentage against an average team on a neutral court – and adjusted offensive and defensive efficiencies + tempo.

Rating functions:


toRvik ships with a number of functions that explore detailed player statistics. Notably, bart_player_game provides box and advanced statistics by player for nearly 70,000 Division I games back to the 2008 season. Season-long statistics are available with bart_player_season and bart_player_splits. The latter will split granular player statistics by game result, type, location, or month.

Unprecedented access to transfer and recruiting histories are available with transfer_portal and player_recruiting_rankings. Powered by Verbal Commits, toRvik provides the transfer histories of over 5,000 players back to the 2012 season, while individual recruiting rankings from 247Sports, ESPN, and Rivals are provided for over 6,000 players back to 2008.

Player functions:


The package exports several functions that focus on team statistics and histories. bart_team_box returns aggregate and per-game box totals on four splits: Game result, type, location, and month. bart_team_shooting will return team shooting performance on a number of on-court location ‘bins,’ including dunks, close two, far two, and three-point field goals. As for history, bart_team_history returns a tidy look at per-season results and four factors.

Team functions:


toRvik pulls detailed game data with several functions. bart_game_box returns box statistics and game information; back to the 2019 season, it will also return second chance points, points off turnovers and from the becnh, points in the paint, fast break points, and basic score data (biggest lead, biggest run, time leading, and NET quadrant).

bart_game_prediction leverages Barttorvik’s industry-leading game predictor model to return expected possessions, points, and win percentage for any game on any date at any location back to 2015. bart_tournament_prediction will randomly simulate single-elimination tournaments on any date.

Game functions:


toRvik offers three functions that explore historical and expected tournament performance. bart_tournament_results returns both traditional raw results and seed- and strength-adjusted performance by team, conference, NCAA seed, and coach back to 2000. bart_tourney_sheets returns the same quality and predictive metrics that are taken into consideration by the NCAA selection committee.

Tournament functions:
