Summary:
stan_gamm4: how to extract smooth data ("average" and "by condition")
Description:
Considering your vignette example for gamm4, I'd like to know if (and how) it's possible to extract a dataframe containing the values of the smooth.
That would be nice to further implement experimental methods (such as here) to identify "periods of change" or points of curve break.
Also, is it possible to extract these smooth curves for each condition (in your example, for each treatment) ? Plotting these different smooth lines would be helpful (and useful for effect illustration).
Thanks a lot for this amazing package 😄

Research direction
Start with the linked gamm4 vignette and the rstanarm gamm4 example. Determine whether smooth values can be extracted as a data frame both overall and separately by treatment condition, then document the supported approach or limitation and demonstrate the result with the example.
