nfl4th 1.0.7

• Further improvements to internal cache handling by CRAN request. (#56)

nfl4th 1.0.6

• The internal cache is now aware of changed model formats and forces a model update for compatibility with xgboost (>= v3). (#53)

Thank you to @isaactpetersen, and @mrcaseb for their questions, feedback, and contributions towards this release.

nfl4th 1.0.5

• Stop letting roof break things
• New location for pre-computed numbers
• Re-work field goal model. Takes into account improvements in accuracy (especially on long kicks) and gives probability > 0 on kicks of over 70 yards
• Update models and internals to be compatible with newer xgboost (>= v3) versions. (#41)
• nfl4th now requires R 4.1 to allow the package to use R’s native pipe |> operator. This follows the Tidyverse R version support rules. (#43)

nfl4th 1.0.4

• Create package cache directory with tools::R_user_dir() because CRAN doesn’t like rappdirs::user_cache_dir()

nfl4th 1.0.3

• Re-export xgboost models to get rid of annoying warning message
• Tweak how close to end of game it will calculate probabilities
• Required data isn’t loaded directly with the package. Instead the download is triggered when necessary and cached in a local package cache. The cache can be cleared with the new function nfl4th_clear_cache(). The package resets the cache partly when loaded. This can be prevented with options(nfl4th.keep_games = TRUE).
• Update win probability model. Instead of only using nflfastR, it stacks nflfastR with another model
• Fixup cache paths.
• Remove tidyverse from Suggests

nfl4th 1.0.2

• Nothing changed. Forced update to documentation to not get kicked off CRAN

nfl4th 1.0.1

• Fix for aborted plays on punts being called going for it
• Re-categorized some plays as unknown (i.e., NA) go: False Start or defensive encroachment along with being lined up to go for it (run formation or pass formation)
• Added fast argument to load_4th_pbp() which allows for loading pre-computed go_boost rather than needing to calculate it

nfl4th 1.0.0

• Initial public release

nfl4th 0.0.0.9000

• Release as package
• Fixes with touchdowns. Instead of granting 7 points, assumes teams choose best option between PAT or 2pt and give pre-conversion attempt WP accordingly
• Fix for punt WP at the end of first half being too high
• Add logic for TD/FG decision on the last play of the first half
• Add possibility for muffed punt
• Reduce field goal chances on very long field goals
