Table 1: Package characteristics. Blue cross is for option available for a given type of model in the package on CRAN, orange cross is for option included in the package but not on CRAN yet. Empty cells mean that an option is not available for a given type of model (either not coded yet or simply not applicable). RE = Recurrent Event; TE = Terminal Event; LO = Longitudinal Outcome; STE = Surrogate threshold effect; ODE = Ordinary Differential Equation; GSM = Generalized Survival Model; PHM = Proportional Hazards Model; AHM = Additive Hazards Model; POM = Proportional Odds Model; PROM = Probit Model.

A shiny application of frailtypack is available, allowing modelisation and prediction of several models presents in frailtypack, at https://frailtypack-pkg.shinyapps.io/shiny_frailtypack/ This application can be run in a local mode in R thanks to the function runShiny().
If you want to take in charge frailtypack as a project, but work on a macOSX with a version of R >= 3.6, a problem must happen between openmp and clang. clang does not seem to support option '-fopenmp'. To avoid this, you should edit your personal Makevars (~/.R/Makevars), admitting you use gfortran, by relocating CC=clang by CC=gfortran
