 The experts array is a bit more complicated. C++ expects us to pass a list of arrays. Thereby, the list itself must have dimension `Tx1` and the elements of the list (the arrays) `D x P x K`. For convenience we can use `init_experts_list()` to create such a list from our experts array.
 
 ```{r}
-model$experts <- init_experts_list(experts, y)

 Now suppose we want to alter the smoothing behavior across quantiles. We start by creating a new hat matrix.
