Prefixing output columns which are returned as Dataframe

Specific Domains Data
,
10

Based on a master’s solution here, I have adapted the code to handle it:

using DataFrames

function calc(x1,x2, suffix)
  y1 = accumulate(+, x1+x2 .+ 0.1rand())
  y2 = accumulate(*, y1)
  y3 = accumulate(+, y2 ./ x1)
  mynames = Symbol.((:y1, :y2, :y3), "_$suffix")
  return (;zip(mynames, (y1,y2,y3))...)
end

d = DataFrame(x1=rand(100), x2=rand(100))

hcat(d, DataFrame(calc(d.x1, d.x2, "mycalc")))
