fuzzystring: Fast fuzzy string joins for data frames

fuzzystring provides fuzzy inner, left, right, full, semi, and anti joins for data.frame and data.table objects using approximate string matching. It combines stringdist metrics with a data.table backend and compiled C++ result assembly to reduce overhead in large joins while preserving familiar join semantics.

Details

Main entry points are fuzzystring_join() and the convenience wrappers fuzzystring_inner_join(), fuzzystring_left_join(), fuzzystring_right_join(), fuzzystring_full_join(), fuzzystring_semi_join(), and fuzzystring_anti_join().

The package also includes the example dataset misspellings.
