longDF2ratetable

value.var

names vector of variables by which to create (array) dimensions

by.vars


Coerces a long-format <code>data.frame</code> of population hazards
to an array, and in turn to a <code><a rd-options="survival" href="/link/ratetable?package=popEpi&version=0.3.1&to=survival" data-mini-rdoc="survival::ratetable">ratetable</a></code>,
which can be used in e.g. <span class="pkg">survival</span>'s expected survival computations
and <span class="pkg">relsurv</span>'s relative survival computations.


Enables computation of various epidemiological statistics where the use of population data such as population counts and hazards is required.
Relatively high computation speed achieved by using data.table.
