In an example (
http://rpubs.com/bbolker/3324 ), I wanted to (1)
overlay boxplots and violin plots, (2) use facet_wrap with free scales
to get separate scaling for each variable, (3) lay the figure out
horizontally (i.e. horizontal boxplots and violins).
I think this is a fairly well known issue, e.g.
https://github.com/hadley/ggplot2/issues/95
The last time I encountered this I created a new, horizontal version
of the geom I wanted (I think it was geom_hlinerange), but in this
case I would have to modify both geom_boxplot and geom_violin, and
they're both a bit more complex than linerange (so more chances to
screw up), so I thought I would ask whether a fix was on the horizon
or whether someone else had a workaround that I haven't thought of ...
thanks
