Changelog • hockeyR

fixed calculate_individual to ensure players with 0 shot events recorded still show up in final stats data (affects individual game stats mostly)
removed polite dependency, shifted to entirely rvest scraping
added checks to fix failing hockey-reference scrapers
removed lingering native pipe from readme and scrape_game
fixed incorrect color code in team_logos_colors (#6)

New functions added

calculate_toi calculates the time on ice for all skaters in a supplied play-by-play set
calculate_on_ice calculates player on-ice statistics for all skaters in a supplied play-by-play set
calculate_individual calculates player individual statistics for all skaters in a supplied play-by-play set
get_standings pulls standings and team stats for given seasons from NHL.com

Function updates

get_game_ids now returns column for scheduled start time for each game
%not_in% operator now defined globally within package

Bug fixes

get_draft_class now works for classes prior to 1983 (first year player IDs existed)

New addition:

Play-by-play data loaded through load_pbp includes new column for expected goals
Details on & code to create the hockeyR expected goals model can be found here
The scrape_game function has been adjusted to automatically add expected goals to the output

New function:

calculate_xg adds expected goals column to pbp data (used inside scrape_game, not necessary to use this to get expected goal values)

Fixes:

Changed the player_id column in get_draft_class to prospect_id - proper NHL player_id column only returns with player_details set to TRUE

The scrape_game() function runs about 4x faster now

Three new functions have been added:

get_team_roster() fetches the current roster for a single team from nhl.com
get_current_rosters() fetches current rosters for all 32 teams from nhl.com
get_draft_class() fetches all draft selections for a single draft year from nhl.com

Updated get_game_info() & get_game_rosters() functions to require game_id as the argument rather than raw json data
Updated scrape_game() function to accommodate above changes
Added get_goalie_stats() function to scrape season goalie stats from hockey-reference.com
Added get_skater_stats() function to scrape season skater stats from hockey-reference.com

Fixed issue in hockey-reference scraper where page exists but no stats recorded throws error (issue was breaking the hockey-ref-scrapers vignette)

Updated to use the magrittr pipe operator %>% rather than the native R |>
Walked back R dependency from 4.1.0 to 3.5.0 by switching pipes

Updated DESCRIPTION to include R 4.1.0 dependency (#1)
Added httr dependency for load_pbp() function
Moved hockey-ref examples from README to a vignette
Submitted to CRAN

Added a NEWS.md file to track changes to the package.
