Bayesplot suggestions

Hi!

I like bayesplot and try to use it for most of my plotting tasks. Here are a few cases which could be considered:

  • ppc_* are great functions for model checking, but sometimes I want to show predictions of the model in absence of data. Could we make the y argument optional? Right now I just pass in the median of yrep so that it does not bother me, but I think this would be generally a good thing to be able to plot model predictions.

  • ppc_intervals (+ribbon) … how about a prob_outer argument just like mcmc_intervals?

  • I really like the “x” argument in ppc_intervals/ribbon; more if these in other functions if sensible would be great.

If this sounds reasonable I am happy to transfer these as issues to the bayesplot repo.

Best,
Sebastian

This is one of those posts which I cannot edit.

So what I wanted to add: Maybe I am looking for a “x” argument for mcmc_intervals? In addition I would also like to use a mcmc_ribbon function if it would exist (in a grouped variant as well and with a “x” argument).

Sounds reasonable to me! Issues would be great.
