The goal of this vignette is to provide a quick overview of using the PanelMatch package, highlight important features and functions, and help users get the most out of their experience with the package. It assumes that you have been able to install the package successfully and are already familiar with the basics of R.

We will be working with the dem data set, which comes included with the package. Before doing any matching, estimation or further analysis, it is helpful to understand the distribution of the treatment variable within your data set. The package hopes to facilitate this with the `DisplayTreatment function.

DisplayTreatment( = "wbcode2",
        = "year", legend.position = "none",
                 xlab = "year", ylab = "Country Code",
                 treatment = "dem", data = dem)
