stby

a grouping variable or a list of grouping variables,
each of length nrow(data).

INDICES

Logical. Essentially a placeholder to maintain full
compatibility with base by. For more details, see 
<code><a rd-options="base" href="/link/tapply?package=summarytools&version=1.0.1&to=base" data-mini-rdoc="base::tapply">tapply</a></code>.

simplify

This is essentially the base <code><a href="/link/by?package=summarytools&version=1.0.1" data-mini-rdoc="summarytools::by">by</a></code> function, except for the 
class of the returned object.

utilities

Data frame summaries, cross-tabulations,
weight-enabled frequency tables and common descriptive
(univariate) statistics in concise tables available in a
variety of formats (plain ASCII, Markdown and HTML). A good
point-of-entry for exploring data, both for experienced
and new R users.
