> We would like to announce a new package called "gcmrec". This package fits the parameters for the general semiparametric model for recurrent events proposed by Peña and Hollander (2004). This class of models  incorporates an effective age function which encodes the changes that occur after each event occurrence such as the impact of an intervention, it allows for the modeling of the impact of accumulating  event occurrences on the unit, it admits a link function in which the effect of possibly  time-dependent covariates are incorporated, and it allows the incorporation of unobservable  frailty components which induce dependencies among the inter-event times for each unit.
