Rebuild brmsfit from cmdstan CSV files

I fit a model using brms some time ago. Now on my computer I can find the CSV files containing the draws (using the cmdstanr backend) but not the associated brmsfit object. I still have the script that includes my call to brms. Is there a good way to rebuild the brmsfit object using the original call and the saved CSVs without refitting?


You can try to load the CSV via cmdstanr, creat an empty brmsfit object and then combine the two by copying code over from brms:::.fit_model_cmdstanr (see brms/backends.R at master · paul-buerkner/brms · GitHub for the code). Not the most elegant solution but I don’t have a move convenient idea right now.
