Make "ggs" understand "stanreg" objects in addition to "stanfit" (feature suggestion)

[stefanherzog]

It would be great if ggs could import "stanreg" objects generated by the rstanarm R package in addition to the generic "stanfit" objects. Thanks!

[xfim]

Sure, @stefanherzog . I will work on it. Thank you for the suggestion. I simply assumed that rstanarm objects were stanfit, without checking.

@xfim : Thanks so much!

Solved at commit b6bdf968. Please, @stefanherzog, test it to check that it works under different circumstances.

@xfim : Thanks!

While trying to test the new version (addressing #52 and #53), I couldn't install the latest version using

devtools::install_github("xfim/ggmcmc")

I got the following error:

However, dplyr 0.4.3 seems to be the latest release available.

Here's my session info

Yes, this is a known situation. The issue is that the development version of ggmcmc relies on the development version of dplyr right now. I am waiting for dplyr to be stabilized (therefore, greater than the current 0.4.3) to stabilize ggmcmc as well.

So now I have changed the requirement again to lower it, so that you can compile it, but please be sure that you use the dplyr version as well.
