The RECLAC Python package provides functions to compute recurrence lacunarity as described in [braun2021] (Open Source). Its functionality is very basic at the current stage and will probably be extended in the near future. It also offers a basic implementation of traditional recurrence quantification measures and computation of box-counting dimensions.

Install from PyPi by simply typing

pip install RECLAC

in your console.
