corrplot doesn't support DataFrames

[diegozea]

LoadError: MethodError:corrplothas no method matching corrplot(::DataFrames.DataFrame)

This should probably be a Plots issue... passing in a DataFrame to any plotting command, but without any column labels, should plot one series per column.

I'm also facing same issue

julia> using RDatasets
julia> using MLPlots
julia> iris=dataset("datasets", "iris")
julia> corrplot(iris)
ERROR: MethodError: `corrplot` has no method matching corrplot(::DataFrames.DataFrame)

Maybe you should add Requires.jl https://github.com/MikeInnes/Requires.jl to help to fix that

To be clear... this isn't a bug... it's a not-yet-implemented feature. I should note that I plan on rewriting corrplot as a "user recipe" and moving it to PlotRecipes.jl.

I'm not sure what you think that would accomplish...

To my understanding if you add Requires.jl as requirement, you will be able to have code that can take DataFrame as input (even if DataFrames.jl is not installed). So it's a good way to have optional dependencies.

Yeah I know about Requires (btw DataFrames is already an optional
dependency). It just doesn't make any sense as a solution. We're just missing
a dataframe-specific feature.

To me Requires seems like an unclean solution nowadays

[scls19fr]

a=Array(iris[[:SepalLength,:SepalWidth,:PetalLength,:PetalWidth]])
corrplot(a)

Unfortunatelly I haven't found a way to define points color by Species.

Setting axes name will also be a great feature to have.

See: JuliaPlots/GraphRecipes.jl#1

Any feature requests for the corrplot recipe should be made there.
