Decomposition of (income) inequality by population sub groups.
For a decomposition on a single variable the mean log deviation can be used
(see Mookherjee Shorrocks (1982) <DOI:10.2307/2232673>).
For a decomposition on multiple variables a regression based technique can be
used (see Fields (2003) <DOI:10.1016/s0147-9121(03)22001-x>).
Recentered influence function regression for marginal effects of the (income
or wealth) distribution  (see Firpo et al. (2009) <DOI:10.3982/ECTA6822>).
Some extensions to inequality functions to handle weights and/or missings.

A Toolkit for Year-Quarter and Year-Month Dates
S3 classes and methods to create and work with year-quarter and year-month
vectors. Basic arithmetic operations (such as adding and subtracting) are
supported, as well as formatting and converting to and from standard R
Date types.
