R Code and References

• Curtis Kephart's Lessons on R
• A great intro for newcomers to R.
• R Functions
• Balance.Table -- Creates a balance table (or "comparison of means" table) to ensure balance between treatment and control groups.
• RDbalance.table -- Create a balance table with regression discontinuity estimates across the threshold
• Regout -- Easier clustering of standard errors with Stargazer output.
• IV.Estimate -- Easily calculate standard errors of the IV estimates in a two-staged least squares context.
• RDplotr -- Create many regression discontinuity plots and save them.
• A primer on dplyr and tidyr
• These packages are my preferred method for data manipulation in R, part of the tidyverse.
