…data.table

At its core, data.table provides an enhanced version of data.frames that are faster, more memory efficient and can be manipulated using a more concise syntax. It also provides a whole set of extra functions for reading from and writing to tabular files, reshaping data between long and wide formats, joining data sets and much more.

data.table mascot is a sea lion, which barks “R R R”
