Implement bar_chart_means #9
Description
Should we do this? It was in the old issue tracker, here's the discussion.
- bar_chart_means to go with the existing bar_chart_counts.
- In progress in the "bar_chart_means" branch if anyone wants in.
- Thought 2/13 (Sam): should this be bar_chart_identity? It'll be a simpler function, and more flexible as the user could calculate median or something else. Is that worth asking the user to pre-calculate a data.frame of means?
