ncaavolleyballr 0.5.1

• The 2025 women’s volleyball season has completed, so we have added Division 1 data to the data page. The NCAA is making it very difficult to scrape lots of data at once, so we don’t have Divisions 2 or 3 uploaded yet.

• To help with the scraping we have added a delay argument to the group_stats() function (and downstream conference_stats() and division_stats() wrappers) that allows control over the time delay between scraping the next team/contest.

• The output of play-by-play data now has a column counting each rally and each event within a rally to address #20.

ncaavolleyballr 0.5.0

• The 2025 season has begun, and this version has updated the current_season() to 2025 to allow scraping this season’s data.

• The package website now includes a data page that includes all data from 2020-2024 as separate files for each sport, data level, division, and year.

• Data output now includes contest ID or team ID columns to facilitate joining datasets.

• Most of NCAA’s websites now using JavaScript with loading pages, so most functions now use rvest::read_live_html(). Unfortunately, this has resulted in much slower processing of data, and large-scale scraping triggers IP address bans. When encountering errors, try running the function again or at a later time.

Package development

• Chromote sessions are now closed after scraping data.

• Unit testing is greatly expanded and improved to test the code better.

• Documentation uses inherited notes to simplify documentation changes.

• Air is now used to format code.

ncaavolleyballr 0.4.3

• NCAA’s game-by-game website introduced a loading page that disrupted team_season_stats() and team_match_stats(). team_season_stats() now gets the info from a different page. team_match_stats() now uses the rvest::read_live_html() function, which requires the {chromote} package and access to Google Chrome.

• Catch contests with too many sets and return warning instead of error
