irates. irates returns an object with which further measures can be determined, e.g., incidence rate ratios (irates.ratio), incidence proportions (iprop) or the cumulative incidence function (cif). The latter can easily be plotted using CIFplot. Also, a multistate type graphic based on incidence rates can be plotted by plot.irates.
