A collection of functions for the analysis of archaeological mortality data (on the topic see e.g. Chamberlain 2006 < https://books.google.de/books?id=nG5FoO_becAC&lpg=PA27&ots=LG0b_xrx6O&dq=life%20table%20archaeology&pg=PA27#v=onepage&q&f=false>). It takes demographic data in different formats and displays the result in a standard life table as well as plots the relevant indices (percentage of deaths, survivorship, probability of death, life expectancy, percentage of population).
mortAAR you can calculate a life table based on archaeological demographic data. You just need the number of people of a certain age, but you can also use single individual data.
mortAAR allows to separate the data according to sex/location/epoch or any other grouping variable.
What is a life table [aka discrete time survival analysis]? According to Chamberlain it is a

mortAAR for R together. We hope it will be of use for archaeologists world-wide.
In our view,
mortAAR shines in the following areas:
