xref #183 for categorical colorbar

Try `color = :Species => ""` and then probably `legend = (; titleposition = :left)` in `draw`.

... and (if that doesn't work yet) also allow renaming?

thanks for the hint. I'll see how far I get. As far as Juno is concerned, probably this: https://github.com/JuliaInterop/RCall.jl/blob/master/src/ijulia.jl

I think I got it to work. ```julia using RCall, DataFrames @rlibrary ggplot2 df_string = DataFrame(x = randn(100), y=randn(100), z1=rand(["a"; "b"], 100), z2=rand(["darkorange"; "lightblue"], 100)) plt = ggplot(df_string) + geom_point(aes(x=:x,...

Thank you for your help! Regarding > You probably can't do any better, but for correctness you'll need to figure out a runtime check for whether you have a R-plot,...

Now that I understand that `R-base` plots cannot be captured ex-post, I start to understand what the code in `ijulia.jl` does. 1. It resets the default `device` so that plots...

for me this still segfaults. I am on Ubuntu 18,04, Julia 1.4, RCall 13.6 Error message ``` signal (11): Speicherzugriffsfehler in expression starting at REPL[4]:0 dgemv_ at /usr/lib/x86_64-linux-gnu/libblas.so.3 (unknown line)...

i made RCall reinstall R with ```julia ENV["R_HOME"] = "*" using Pkg Pkg.build("RCall") ``` and now it works. No more segfaults :-)

Sorry, I guess I mixed that up. I guess I meant that `Vector{Symbol}` arise naturally and they don't work well with `RCall`.
