Important! The commarobust package is no longer in development. I'll leave this branch up in case folks want to still use it or have legacy code. But anything you could do in commarobust you can do much better in estimatr.

Install estimatr:

install.packages("estimatr")

If you need the legacy version of commarobust, use:

remotes::install_github("acoppock/commarobust", ref = "legacy")
