🚀 How to Use

1. Clone or download the repository
   Use GitHub Desktop or download as ZIP.

2. Open in RStudio as a Project
   It's recommended to open this folder as an RStudio project for easy file management and sourcing.

3. Run projection scrapes
   Open scripts/scrape_projections.R and click “Source” in RStudio to generate fantasy projections.

4. Edit and run the optimizer
   Open example_usage.R, adjust the parameters (budget, roster size, scoring format, etc.), and run the script.

5. View your results
   The console will show:

   • Your optimized roster under salary and positional constraints
   • Total projected points and cost

🧠 Notes

• The optimizer uses Rglpk::Rglpk_solve_LP() to maximize projected points under auction draft constraints.
• You can simulate realistic league behavior by inflating top-tier player values (e.g., top 5 RBs or WRs).
• The script automatically subtracts $1 per bench/K/DST spot to ensure your budget doesn’t exceed league rules.

🧰 Requirements

• R packages:
  • tidyverse
  • Rglpk
  • ffanalytics (used in projection scraping)

Install with:

install.packages(c("tidyverse", "Rglpk"))
# ffanalytics is available from GitHub
install.packages("remotes")
remotes::install_github("FantasyFootballAnalytics/ffanalytics")
