Error in re-building vignettes:

Loading required package: Rcpp
rstanarm (Version 2.17.4, packaged: 2018-04-13 01:51:52 UTC)
- Do not expect the default priors to remain the same in future rstanarm versions.
Thus, R scripts should specify priors explicitly, even if they are just the defaults.
- For execution on a local, multicore CPU with excess RAM we recommend calling
options(mc.cores = parallel::detectCores())
- Plotting theme set to bayesplot::theme_default().
NOTE: As of emmeans versions > 1.2.3,
      The 'cld' function will be deprecated in favor of 'CLD'.
      You may use 'cld' only if you have package:multcomp attached.
