simrec allows simulation of recurrent event data following the multiplicative intensity model described in Andersen and Gill (1982), with the baseline hazard being a function of the total/calendar time.

To induce between-subject-heterogeneity, a random effect covariate (frailty term) can be incorporated.

Furthermore, viasimreccomp simulation of data following a multistate model with recurrent event data of one type and a competing event is possible.

simrecint gives the possibility to additionally simulate a recruitment time for each individual and cut the data to an interim data set.

WithsimrecPlot andsimreccompPlot the data can be plotted.
