Error: passing unknown arguments: warmup in stan_jm()

[Devashish13]

Summary:

not able to set warmup parameter in Stan_jm() function

Description:

When I am trying to change default warmup parameter, stan_jm() giving an Error: passing unknown arguments: warmup. In sampling function from rstan I can see the warmup parameter with default value floor(iter/2)

Reproducible Steps:

The code I am running from the example section in rstanarm

f1 <- stan_jm(formulaLong = logBili ~ year + (1 | id), dataLong = pbcLong, formulaEvent = Surv(futimeYears, death) ~ sex + trt, dataEvent = pbcSurv, time_var = "year", # this next line is only to keep the example small in size! chains = 1, cores = 1, algorithm = "sampling",seed = 12345, iter = 1000,warmup = 100)

RStanARM Version:

2.21.3

R Version:

4.2.1

Operating System:

macOS Monterey 12.5

Might help to see the full traceback? Is the error coming from rstanarm itself, or possibly from rstan?

Could this be incompatibility with a recent release of rstan (although looks like one hasn't been release to CRAN since April... https://cran.r-project.org/web/packages/rstan/index.html)?
