`shinystan news`

Version 2.1.1

Introduce drop_parameters function for removing parameters from a shinystan object (useful for very large objects when you only want to look at a subset of parameters).
Add rstanarm to Suggests (in the DESCRIPTION file) so rstanarm::pp_check can be called.

Version 2.1.0

Compatibility with recent ggplot2 update
Select parameters via regular expressions in parameters plot ('Estimate' page)
Fix error when selecting an entire parameter group in parameters plot ('Estimate' page)

Version 2.0.1

Fixes small bugs and typos
Adds support for stanreg objects
Moves ggplot2 from Depends to Imports

Version 2.0.0 (major update, initial CRAN release)

Version 2.0.0 has a new look, a new(ish) name, and a lot of new functionality. Many bugs have also been fixed (see GitHub issue tracker).

Available on CRAN.

New names

The name of the R package is shinystan and the app/GUI is ShinyStan.

Deploy ShinyStan apps to shinyapps.io (RStudio's ShinyApps service)

The deploy_shinystan function lets you easily deploy ShinyStan apps to RStudio's shinyapps.io for any of your models. Each of your apps (i.e. each of your models) will have a unique url.
