ddply is present on H2OFrame documentation. However I can't find it.

I have the version 3.22.0.1 which I downloaded at here. The in the source code of this .whl I can't find ddply. However, in the documentation page, we see a link for the source code that contains ddply.

I wonder if ddply was removed, or if it is just present for h2o in R, or if it is just present in the enterprise version.

Why I can't find it?

ddply is not available in the python api, you are linking to out-of-date documentation.

For the latest stable documentation please see this link: http://docs.h2o.ai/h2o/latest-stable/h2o-py/docs/index.html (and for 3.22.0.1 see http://h2o-release.s3.amazonaws.com/h2o/rel-xia/1/docs-website/h2o-py/docs/index.html).

  • Could you help me with this: Let's say I have a data frame with the meals I ate over each day of a week for the entire month. I wish I could group it per week day, and make a list of all the meals, e.g. Monday: [eggs, milk, pasta]. How could I do this in python with h2o or spark dataframe? – Eduardo Reis Nov 16 '18 at 19:39
  • as a first quick attempt you could try using h2o's group_by method. please this link for a few examples of using group by in h2o python: http://docs.h2o.ai/h2o/latest-stable/h2o-docs/data-munging/groupby.html. – Lauren Nov 16 '18 at 20:17
  • I ended up using only spark because for me the h2o group_by seems to be very limited to those built-in operations. – Eduardo Reis Nov 20 '18 at 22:48
