Hi Matthew,

CRAN complains about changes to worse in tidybayes with the new brms version. Can you perhaps check what is going on?

All the best Paul

Dear maintainer,

package brms_2.20.1.tar.gz has been auto-processed. The auto-check found problems when checking the first order strong reverse dependencies. Please reply-all and explain: Is this expected or do you need to fix anything in your package? If expected, have all maintainers of affected packages been informed well in advance? Are there false positives in our results?

This appears to be due to the change in default value for the method parameter of residuals.brmsfit from "posterior_epred" to "posterior_predict" on line 92 here: https://github.com/paul-buerkner/brms/commit/4139e7fedcddf8959d00632fb42ab1fee98235f6

(I couldn't find a mention of this in NEWS, but was able to figure it out using git blame).

I fixed my test and will submit a fixed version of tidybayes to CRAN. I'll update here when that's done.

[paul-buerkner]

Thank you and sorry for causing any extra work!

[mjskay]

No prob! It was an excuse to fix another bug anyway :).

[mjskay]

Submitted to CRAN. I will update here when it is accepted.

[mjskay]

Fixed version of tidybayes (3.0.6) has been accepted and is on its way to CRAN.

[paul-buerkner]

Perfect, thank you!!
