transform(deprecated)/tally - Help

stats[transform, tally]

group together data of same value

 Calling Sequence stats[transform, tally](data) transform[tally](data)

Parameters

 data - statistical list

Description

 • Important: The stats package has been deprecated. Use the superseding package Statistics instead.
 • The tally function of the subpackage stats[transform, ...] groups together the items of data that have the same value.
 • The ordering of the result is unpredictable. The utility stats[transform, statsort] can be useful.
 • To regroup data into a particular target pattern, use stats[transform, tallyinto].
