[julia-users] KeyError when trying to access a column of the dataframes iteratively

[varun7rs]

Hi,

I seem to have run into a problem here. I firstly have a function as 
follows:

function gen(type, frame1, frame2)

  x = frame1[:type]
  z = frame2[:type]
  y = []
 
  for i in length(frame1)

    push!(y, x[i] * z[i])

  end

end

Now, when I call:   ans = gen(I, frame1, frame2), I get a keyError saying 
type not found.

sample dataframe

dataframe1

Row I  II III IV V
1    0.2   0.4   0.6   0.7   0.4
2 .....
3....
.
.
.
Can you please let me know where I'm making a mistake and how I can fix it? 
Thanks guys
