Running a fairly simple model in rstan. The chains run, and no errors are reported. However, at the end of the run, I get what looks like an R error. Additionally, the
object that should contain the samples is empty.
The error is:
Elapsed Time: 2811.41 seconds (Warm-up) 2038.34 seconds (Sampling) 4849.75 seconds (Total) Error in FUN(X[[i]], ...) : trying to get slot "mode" from an object (class "try-error") that is not an S4 object In addition: Warning message: In parallel::mclapply(1:chains, FUN = callFun, mc.preschedule = FALSE, : 4 function calls resulted in an error.
R version 3.4.0
rstan version 2.15.1
Command that caused error:
post <- stan(“model.stan”, data = datlist, chains = 4, save_warmup = FALSE, refresh=1, iter = 1000, init_r = 0.1, control = list(adapt_delta = 0.9, max_treedepth = 8))
Is this something I may have caused, or is there a bug in rstan?
