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=0.4.3&to=survival" data-mini-rdoc="survival::ratetable">ratetable</a></code>,
which can be used in e.g. survival's expected survival computations
and relsurv's relative survival computations.

Enables computation of epidemiological statistics where e.g.
counts or mortality rates of the reference population are used. Currently
supported: excess hazard models, rates, mean survival times, relative
survival, as well as standardized incidence and mortality ratios (SIRs/SMRs),
all of which can be easily adjusted for e.g. age.
Fast splitting and aggregation of 'Lexis' objects (from package 'Epi')
and other computations achieved using 'data.table'.

longDF2ratetable function

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='ratetable'>ratetable</a></code>,
which can be used in e.g. survival's expected survival computations
and relsurv's relative survival computations.
