Error fitting MMRM (draw step)

[tronieri]

Hi all, I am using rbmi for the first time and am not able to get the draws step to work. I was using my own data but could not get around the issue so I tried running it with the antidepressant_data vignette and have the same problem. Here is what I keep seeing:

set.seed(987)
drawObj <- draws(
data = dat,
data_ice = dat_ice,
vars = vars,
method = method,
quiet = TRUE
)

Error in fit_mcmc(designmat = model_df_scaled[, -1, drop = FALSE], outcome = model_df_scaled[, :
Fitting MMRM to original dataset failed

I have loaded rbmi (1.4.1) and stan (2.32.7) and am using R version 4.4.3. I followed all other vignette steps and they appeared to run correctly. Is there any other package that might be required or any other model specifications that I can add that will solve this problem?
Thank you.

Hi @tronieri, thanks for your bug report. As a first step, could you please also post the output of sessionInfo()?

All the examples I have + the vignettes run fine on my work machine (MacOS) as well as my personal machine (Fedora). I'm not able to re-produce this issue. Please can you provide further details otherwise I'll have to close this issue.
