Tries, or radix trees, are key-value data structures optimised for very, very fast matching of the keys against user-provided data (and then the return of the associated values!)

This is pretty useful in data cleaning and value extraction, and tries let you do it really efficiently. triebeard contains an implementation that can be used both when writing R, and when writing Rcpp (and imported and linked against, to boot). For more information see:
