A new paper I worked on is out in Justice Quarterly! I won't speak on the substantive nature of the paper as I worked solely as the methodologist, but I developed a new matching method not otherwise described in the literature, and I want to tell you about it!

For the open source devotees out there, I've integrated @OpenFreeMapOrg into the #rstats {mapgl} package.
Do `maplibre(style = openfreemap_style("liberty"))` for an excellent street map with 3D buildings; "bright" & "positron" are also available.
Map with no API keys required!
