createSurvVar

This function will create survival variables from an existing start variable
date of event variable and last date followed variable

A small group of functions to read in a data dictionary and the
corresponding data table from 'Excel' and to automate the cleaning, re-coding
and creation of simple calculated variables. This package was designed to
be a companion to the macro-enabled 'Excel' template available
on the GitHub site, but works with any similarly-formatted 'Excel' data.
