How to include neff in jagstargets summary

[tatakof]

Hello everyone,

I was wondering if somebody knew how to output a summary table that includes the neff (effective number of samples) of the jags run when using tar_jags.

Thanks!

In the example at https://docs.ropensci.org/jagstargets/articles/introduction.html, tar_read(example_summary_x) has effective sample size in columns ess_bulk and ess_tail. Both are calculated by posterior::summarize_draws(). If you want basic effective sample size instead of posterior::ess_bulk() or posterior::ess_tail(), you can customize the summaries argument of tar_jags(), e.g. summaries = list(ess_basic = ~posterior::ess_basic(.x)).
