I reran a model (below) that I have run successfully but with a larger warmup and more iterations. It seemingly ran normally through all the imputed models and produced a large .rds file, as expected. However, when I try to use the brm(file=…) function to load the new .rds file to my r session, I get the following:
Error in validate_formula(formula, data = data, family = family, autocor = autocor, :
argument “formula” is missing, with no default
Calls: brm → validate_formula
Can anyone figure out what I did to get this missing formula issue?
Thank you for any help that you can provide!
