abstract: A C/C++ based package for advanced data transformation and statistical computing
  in R that is extremely fast, class-agnostic, robust and programmer friendly. Core
  functionality includes a rich set of S3 generic grouped and weighted statistical
  functions for vectors, matrices and data frames, which provide efficient low-level
  vectorizations, OpenMP multithreading, and skip missing values by default. These
  are integrated with fast grouping and ordering algorithms (also callable from C),
  and efficient data manipulation functions. The package also provides a flexible
  and rigorous approach to time series and panel data in R. It further includes fast
  functions for common statistical procedures, detailed (grouped, weighted) summary
  statistics, powerful tools to work with nested data, fast data object conversions,
  functions for memory efficient R programming, and helpers to effectively deal with
  variable labels, attributes, and missing data. It is well integrated with base R
  classes, 'dplyr'/'tibble', 'data.table', 'sf', 'units', 'plm' (panel-series and
  data frames), and 'xts'/'zoo'.
