In Dmunslow/tidyDK: Tidy Draftkings CSV data for easier analysis and visualization

knitr::opts_chunk$set(echo = TRUE)

tidyDK is a set of functions to efficiently ingest and clean draftkings contest and salary files into both wide and long tidy formats. tidyDK enables users to:

• Combines user lineup information with player ownership data in 'contest-details' file
• Converts data to long format (1 row per player, per lineup)
• Provides stand-alone analysis functions that can be used on unmodified draftkings 'contest-details' files
• Analyze live contests to determine late-swap strategy

The package contains NFL play-by-play data back to 1999 As suggested by the package name, it obtains games much faster Includes completion probability (cp), completion percentage over expected (cpoe), and expected yards after the catch (xyac_epa and xyac_mean_yardage) in play-by-play going back to 2006 Includes drive information, including drive starting position and drive result Includes series information, including series number and series success Hosts a repository of play-by-play data going back to 1999 for very quick access Features models for Expected Points, Win Probability, Completion Probability, and Yards After the Catch (see section below) Includes a function update_db() that creates and updates a database

## Install tidyDK from github
devtools::install_github("Dmunslow/tidyDK")

library(tidyDK)

Now, download ze sample file (lets get a function that lists the files in the repo)

# save path
con <- "https://github.com/Dmunslow/tidyDK/raw/main/data/contests/NFL2020_w02_nickel_mxe3_91999281.csv"
sal <- "https://github.com/Dmunslow/tidyDK/raw/main/data/salaries/DKSalaries_NFL2020_Week_02_ms.csv"

lus_long <- get_tidy_lineups(contest_path = con, salary_path = sal, "NFL")

This error message sucks: Player position will be FLEX for those players, and salary data will be NA. Include which player(s) causing issue so one can be excluded from salary if needed.
