Replace subsets by grouping?
mschubert opened this issue · comments
This would provide a group
function that adds a narray_grouped
class to an object and indicates which axis the group is on.
Then, map
, lambda
, split
etc. would be S3 generics where .narray_grouped
would trigger splitting the object in subsets, applying the original function, and assembling the result.
The advantage would be that the code for subsets does not get mangled up in the original functions, hence keeping them simpler and more easily maintainable.
Issues:
- For
lamda
, does one array need to be grouped? All of them? How to tell the difference? (but on the other hand could do different subsets on different axes)
Proposed solution:
- add
map_one
,lambda_one
functions but dolambda
subsets in wrapping, nonarray_grouped
as S3 generic
