to_frame w/ index or query? #5

Closed bridwell closed 8 years ago

bridwell commented 8 years ago

Is there a way to evaluate just a subset of rows from a data frame wrapper? Either via a provided index or query string?

jiffyclub commented 8 years ago

No, but I don't think there's much point to doing that in Orca because you need the entire dataframe present in order to do that kind of selection. It would work the same as you requesting the entire dataframe in your code.

Ok thanks. I guess for these types of columns I should just compute locally w/in a step rather than defining them as orca columns.

I'd need to know more specifics to comment in detail. If it helps you can get individual columns from wrapped dataframes via a couple different mechanisms.
