Add Frame.dropSparseRowsBy #404

Closed sebhofer closed 5 years ago

sebhofer commented 5 years ago

Adds dropSparesRowsBy column functionality. This should make it easier for users to deal with missing values in specific columns, e.g., before grouping by those columns (as suggested by @tpetricek in #380).

Thanks for the new function. It will be very handy to use. Could you add some unit tests under Deedle.Tests\Frame.fs, similar to the current tests of Frame.dropSparseRows?

sebhofer commented 5 years ago

Sure, will try to do so later today.

Looks good to me! Thanks.
