Add "row names" to Data viewer and extend support to other objects such as xts #4120

Open abrahammbs93 opened 3 months ago

It will be a great addition for packages such as zooand xts that use data.frames/matrix and leverage row names attributes.

Including a filter / sorting / aggregation may also be great in general for rownames.

So far the Data viewer dont allow any filtering at all.

We currently look for the row.names attribute when querying info for the data explorer:

We could special case it to use index when dealing with xts/zoo objects.

To add support for filtering we'd want to make sure xts/zoo objects are treated as numbers here:

I believe that zoo/xta support would be a great enabler for econometric and financial applications.

Thanks for you answer
