[R] multistate survival analysis w/ time varying covariates

[gulemeto at sas.upenn.edu]

Hi, I've seen in the NestCohort package that one can do a hazard model with a
binary outcome using covariates. I am interested in multistate hazard models
with time-varying covariates, but can't seem to find this already implemented
in an R package. Is this included somewhere but called something else? I feel
like I've looked all over.

Thanks!
