Featured R Packages

  1. stringi: THE string processing package for R by Marek Gagolewski, with contributions from Bartłomiej Tartanus

    stringi is THE R package for correct, fast, and simple string manipulation in each locale and any native character encoding.

  2. genie: A New, Fast, and Outlier Resistant Hierarchical Clustering Algorithm by Marek Gagolewski, Maciej Bartoszuk, and Anna Cena

    A new hierarchical clustering linkage criterion: the Genie algorithm links two clusters in such a way that a chosen economic inequity measure (e.g., the Gini index) of the cluster sizes does not increase drastically above a given threshold. Benchmarks indicate a high practical usefulness of the introduced method: it most often outperforms the Ward or average linkage in terms of the clustering quality while retaining the single linkage speed.

  3. TurtleGraphics by Anna Cena, Marek Gagolewski, Barbara Zogala-Siudem, Marcin Kosinski, Natalia Potocka

    An implementation of turtle graphics in R. Turtle graphics comes from Papert’s language Logo and has been used to teach concepts of computer programming.
