The goal of fedmatch is to match un-linked datasets. It provides a variety of tools that allow a user to build a custom matching algorithm for their specific application. To get started, see the “Introduction to fedmatch” vignette.
You can view all the vignettes, and the rest of the documentation, on the fedmatch website.
