r-cran-purrr 1.0.1-1 (s390x binary) in ubuntu lunar

 This package provides a complete and consistent functional programming
 toolkit for GNU R.
 .
 Purrr draws inspiration from many related tools:
 .
   * List operations defined in the Haskell prelude
   * Scala's list methods.
   * Functional programming libraries for javascript: underscore.js, lodash
     and lazy.js.
   * rlist, another R package to support working with lists. Similar goals
     but somewhat different philosophy.
