Encapsulated Classes with Reference Semantics

person("Winston", "Chang", role = c("aut", "cre"), email = "winston@stdout.org")

Creates classes with reference semantics, similar to R's built-in
    reference classes. Compared to reference classes, R6 classes are simpler
    and lighter-weight, and they are not built on S4 classes so they do not
    require the methods package. These classes allow public and private
    members, and they support inheritance, even when the classes are defined in
    different packages.

Fast and Portable Character String Processing Facilities

A collection of character string/text/natural language
    processing tools for pattern searching (e.g., with 'Java'-like regular
    expressions or the 'Unicode' collation algorithm), random string generation,
    case mapping, string transliteration, concatenation, sorting, padding,
    wrapping, Unicode normalisation, date-time formatting and parsing,
    and many more. They are fast, consistent, convenient, and -
    thanks to 'ICU' (International Components for Unicode) -
    portable across all locales and platforms. Documentation about 'stringi' is
    provided via its website at <https://stringi.gagolewski.com/> and
    the paper by Gagolewski (2022, <doi:10.18637/jss.v103.i02>).
