The bottomup parameter in callbacks will be calculated for all parameters
of call`` expressions. The parameter to the callbacks are thus a list of lists. This function merges these lists into one that contain a list for each named component in thebottomupparameter. If results are not named in thebottomup` list, they are discarded.
merge_bottomup(bottomup)
| bottomup | List of bottom up analysis results. |
|---|
The vectors from bottomup are concatenated, so one level of lists
will be flattened. Use more lists, like list(list(2), list(3))
if you want to prevent this.
