Tutorial not working (deprecation in dataframes.jl)

[pnadon]

The tutorial page has this error, and I receive the same when attempting to follow it:

Steps taken:

using Gadfly, RDatasets
iris = dataset("datasets", "iris")
p = plot(iris, x=:SepalLength, y=:SepalWidth, Geom.point);

Result

┌ Warning: `getindex(df::DataFrame, col_ind::ColumnIndex)` is deprecated, use `df[!, col_ind]` instead.
│   caller = evalmapping(::DataFrames.DataFrame, ::Symbol) at dataframes.jl:96
└ @ Gadfly ~/build/GiovineItalia/Gadfly.jl/src/dataframes.jl:96

I think #1303 should take care of this.
