I am an avid brms user but I recently updated my R, Rstudio, and packages and now I keep getting errors. The error I keep receiving says that my priors are unused:
Error in .fun(data = .x1, seed = .x2, init = .x3, priors = .x4, iter_sampling = .x5, :
unused argument (priors = .x4)
Here is how I am specifying the priors:
prior(normal(0,100), class = Intercept), prior(normal(0,100), class = b))
Here is my model:
brm(perc_cor ~ Parameter * noise + (1|Subject_ID), data = data_totals, family = gaussian(), priors = priors, chains = 4, cores = 4, backend = "cmdstanr")
When I remove the priors argument from the model, the model runs fine. I can’t figure how what I’m doing wrong in assigning the priors. Any help is greatly appreciated!
