DAG: Graph not updating after push

1

After pushing (while having the DAG window opened), the graph in the DAG window does not update, neither automatically nor after pressing `Ctrl+R` (for refreshing). It only updates after closing...

Setting argument "selected" of updateSelectInput() to nonexisting value

2

When using `updateSelectInput()` for a `selectInput()` which does not have a choose prompt and setting argument `selected` (of `updateSelectInput()`) to something which does not exist among the choices of argument...

Typo in density of `brms::gen_extreme_value()`?

1

The density of the generalized extreme value distribution (i.e., the `brms::gen_extreme_value()` family) in the [`brms_families`](https://cran.r-project.org/web/packages/brms/vignettes/brms_families.html) vignette (brms v2.17.0) might have a typo in the exponent of $t(y)$: It reads $-1...

`prior_summary()` incorrect after updating a `cumulative()` fit using fewer response categories

1

When `update()`-ing a `cumulative()` fit with a new dataset that contains fewer response categories than the original one, `prior_summary()` still displays all the thresholds from the initial model fit: ```r...

This is similar to #1373, but for `kfold.brmsfit()` instead of `update.brmsfit()`. So here it seems like `kfold.brmsfit()` does not pass all arguments from the original `brm()` call to the K...

`update()`: Arguments (from `...`?) not passed to `brm()`

1

It seems like `update.brmsfit()` does not pass all arguments from the original `brm()` call to the updated `brm()` call (I guess arguments from the ellipsis `...` are missing). For example:...

"Export" of redundant parameters with cmdstanr backend

1

Again, this is not urgent at all, but rather a cosmetic feature request for something I encountered while working on **shinybrms**. And, similar to #1251, this might not be easy...

"Export" of `par_<...>` parameters (`constant()` prior)

4

This is not urgent at all, but rather a cosmetic feature request for something I encountered while working on **shinybrms**. If you use a `constant()` prior (together with estimated parameters...

Scaling of default priors

9

According to [these lines](https://github.com/paul-buerkner/brms/blob/34e769072e4853c86c2fbf150f603b0e2f5feb2b/R/priors.R#L1090-L1093), it seems like that for a non-factor-like `y` with a link function from , the scale of the default Student-t prior is set to the maximum...

PPC for Cox model

5

A posterior predictive check (PPC) for the Cox model would be nice, but it would probably have to be conducted differently than in all other models since the spline estimate...
