Document / warn re: limitations of ggplot2 pipeline parsing #86

Closed sharlagelfand closed 3 years ago

sharlagelfand commented 3 years ago

There are some limitations re: ggplot2 parsing (and parsing in general!), some are documented in the README:

color mapping is not yet supported
facet_wrap() is not supported - please use facet_grid()
datamations expects different variables in the column and row facets than in the x-axis. datamations generated that do not match this layout may look different than the final plot!
Only geom_point() is supported, e.g. specifying geom_bar() will not produce a bar in the datamation.

There are a couple other things to consider, some other thoughts (will add more here as I start back working on things and think about them!):

If the variables plotted don't match what's grouped / summarised
More than 3 grouping variables

We should document these limitations, and have the function warn or error when something not supported is done.

I have a start on this over in this branch, progress on errors so far:

Error on facet_wrap()
Error when a geom other than geom_point() is used
Error when geom_point() is missing all together

Plus working on supporting color as per #87 - blocked on that right now as per my comment re: allowing multiple variables in splitField
