load_holes() files now carry win_prob,
win_prob_before, wpa (win probability added)
and skill_rating for every hole of every PGA Tour stroke
play event since 2004.add_win_probability() computes the same columns for an
event in progress or for your own hole data.update_db() builds a local SQLite database (or writes
to any DBI connection) from the hosted data, in one schema: every table
has a season column, ShotLink tables carry both PGA Tour
and ESPN IDs, and dates are text. Later runs add missing seasons and
refresh the latest.load_holes() covers 2004 to now (was 2025 to now),
including playoff holes as an extra round.load_player_ids() and load_event_ids()
link ESPN IDs to PGA Tour IDs, so ESPN scoring data joins to ShotLink
and strokes gained.load_logos() returns logo image URLs for tours,
tournaments, ShotLink courses and clubs (every host of a men’s or
women’s major, the Ryder Cup, Presidents Cup or Solheim Cup since 1960),
with PGA Tour, ESPN and ShotLink IDs to join on. Only URLs are provided,
not images.load_witb() returns player equipment from the what’s in
the bag database (WITBDB): one row per club with head, loft, shaft and
grip specs, parsed from GolfWRX and PGA Tour Club Tracker bag posts,
with the source URL of every bag. load_witb_switches()
lists each player’s equipment changes by slot.load_shots() returns every stroke from PGA Tour
ShotLink, 2012 to now: distance, distance to the hole, lie before and
after, play-by-play text, and, in recent seasons, shot coordinates and
launch monitor readings (ball speed, spin, launch angle, apex
height).load_tee_times() returns pairings, tee times and
starting holes for every round.load_course_setup() returns par, yardage and pin
position by hole and round.calculate_strokes_gained() scores every shot against a
bundled baseline of expected strokes by lie and distance, fit from
ShotLink strokes.summarise_strokes_gained() totals shots by round,
tournament or season, adjusted to the field. Season totals track the PGA
Tour’s official strokes gained total closely (correlation 0.97 in 2025
and 0.98 in 2026) and cover every player in the field, not only those
with enough measured rounds.data argument,
so they work directly on tibbles from load_leaderboard():
player_summary("Scheffler", data = load_leaderboard(2025)).player_name,
tournament_id, score_to_par) and older saved
files (display_name, event_id,
score_display) are aligned automatically.save_to_rds() / save_to_parquet()
deduplicate on tournament_id as well as the older
event_id column.load_strokes_gained() gains a year
argument to filter by season.score_to_par of "E" (even
par) is documented.to_par, field_avg (field scoring average on
that hole in that round), vs_field (strokes vs the field
average), and cume_to_par (running tournament score through
each hole, playoff holes included).get_pga_schedule(),
get_tournament_leaderboard(),
get_player_scorecards(), load_pga_schedule(),
load_pga_leaderboards(), and load_pga_hbh()
are deprecated in favor of load_schedule(),
load_leaderboard(), and load_holes(). They
keep working but now warn once per session.options(golfastr.cache = "filesystem") to keep downloads
for 24 hours in the package cache directory, or "off" to
disable caching. The default ("memory") caches for the
current session as before.load_leaderboard() and load_holes() now
load completed PGA Tour tournaments from pre-built files hosted on
GitHub releases (updated daily) instead of querying ESPN tournament by
tournament. Loading a full season of leaderboards drops from minutes to
seconds, and hole-by-hole data now covers the full field rather than
requiring one API request per player.live argument to bypass the
hosted data and fetch directly from ESPN (e.g., for in-progress
tournaments). The live API is also used automatically as a fallback when
hosted data is unavailable.load_holes() output now includes position
(final leaderboard standing) and year columns.data-raw/update_season_data.R pipeline builds and
uploads the hosted files; runs daily via GitHub Actions.load_strokes_gained() with a bundled PGA Tour
strokes gained dataset.tour = "liv".CRAN resubmission with documentation fixes.
