add_wp_variables

Data frame with all of the necessary columns used to estimate
the win probability for a play.

pbp_data

Given a `nflscrapR` play-by-play data frame, calculate the win probability
for a play using the `nflscrapR` win probability model and include 
the columns to the input data frame. See here for an explanation of the 
model methodology: <a href="https://arxiv.org/abs/1802.00998">https://arxiv.org/abs/1802.00998</a>. Source code for 
fitting the model is located here <a href="https://github.com/ryurko/nflscrapR-models/blob/master/R/init_models/init_ep_fg_models.R">https://github.com/ryurko/nflscrapR-models/blob/master/R/init_models/init_ep_fg_models.R</a>.

This package allows data driven sports enthusiasts to use the NFL JSON API data
to perform detailed analysis at game, season, and player levels. The functions within
this package help parse and clean the data from NFL.com for R users. This package was
built to enhance advanced sports analytics research specifically for American football
with the hopes of developing metrics and insights that could potentially be useful for
professional NFL teams as well as the public.
