Using DataFramesMeta.jl [1], the code from the first example turns out pretty similar: using DataFramesMeta, Statistics @chain mtcars begin @select :Cyl :HP groupby(:Cyl) @transform _ begin :dumb_result = myarbitraryfunc.(:HP) :demeaned = :HP .- mean(:HP) end end (mtcars is from RDataSets.jl) [1] https://juliadata.github.io/DataFramesMeta.jl/stable/dplyr/ https://juliadata.github.io/DataFramesMeta.jl/stable/dplyr/
