The analogous operation in tidyjson
is to enter_object
. It can be very useful for discarding the information that you do not care about. I wonder whether there should be a similar option for an array... i.e. "just take the first."
In any case, one of the difficult questions here is: what do you do with rows that do not have this key? I prefer to give that option to the user. They should be able to do either (and we should handle NULL / NA nicely)
It would be very cool to either generate a json_schema object for validation, interpret a json schema object for parsing, or something of that nature. Anything to provide a "nice" default behavior to users.
This is the inverse operation to gather
, spread
, etc. It is desirable to users to write JSON, XML, and other types of nested-list data. It would be great to be able to use similar syntax to invert the cellist
operations. This would transform a tidy dataset and output JSON, XML, or some other nested object.
In tidyjson
, this was called gather_array
or gather_keys
or gather_object
, depending on the context. The basic idea is that you gather the objects in a single row into many rows.
Here we would have the ability to change the objects of a list. i.e. turning character into numeric, etc.
