ncaavolleyballr

Inspired by the NCAA data extraction functions from the {baseballr} package, the goal of {ncaavolleyballr} is to extract women's and men's volleyball information from the NCAA website. The functions in this package can extract team records/schedules and player statistics for the 2020-2024 NCAA women's and men's divisions I, II, and III volleyball teams. Functions can aggregate statistics for teams, conferences, divisions, or custom groups of teams.

Installation

You can install the stable released version of flashr from CRAN with:

install.packages("ncaavolleyballr")

You can install developmental versions from GitHub with:

# install.packages("remotes")
remotes::install_github("JeffreyRStevens/ncaavolleyballr")

Usage

library(ncaavolleyballr)

A suite of functions can be used to extract season, match, and play-by-play data for teams and players. See the Getting Started vignette for a more thorough description of the functions.

Season data

The NCAA uses a unique team ID for each women's and men's volleyball team and season. So to access a team's season data, first you will need to get that ID with the find_team_id(). For instance, to find the ID for Penn State's 2024 season:

find_team_id("Penn St.", 2024)
#> [1] "585406"

With this team ID, you can now extract overall season performance data for the team's players with the player_season_stats().

find_team_id("Penn St.", 2024) |> 
  player_season_stats()

Match data

The NCAA also uses a unique contest ID for each women's and men's volleyball match. The easiest way to get that ID is with find_team_contest(), which returns the contest ID for all matches in a particular season (using the Team ID provided by find_team_id()). For instance, to find the contest ID for 2024 National Championship match between Louisville and Penn State:

find_team_id("Penn St.", 2024) |> 
  find_team_contests() |> 
  tail()

From that, we can see that the contest ID is 6080706. If we pass this contest ID to the player_match_stats() function, we'll get a list with two data frames (one for each team in the contest) that contain player statistics for the match. If we want to get just the Penn State player data, we can set team = "Penn St.".

player_match_stats(contest = "6080706", team = "Penn St.")

Play-by-play data

Play-by-play data are also available with match_pbp(). This returns a data frame with all events and players.

match_pbp(contest = "6080706") |> 
  head(10)

Other functionality

By default, these functions return information on women's teams, but they can be set to return men's information by setting sport = "MVB". You can also aggregate data across conferences, divisions, or custom groups with conference_stats(), division_stats(), and group_stats().
