Hi all, I’m learning Julia and I’m stuck trying to merge several dataframes into only one using a loop.

For instances, suppose that I have 4 dataframes called A, B, C and D. They have the same column names except for the last one, named x4. And I want to merge all of them into one. So far, I’m doing this:

df1=innerjoin(A, B, on = [:x1, :x2, :x3])

df2=innerjoin(df1, C, on = [:x1, :x2, :x3])

df3=innerjoin(df2, D, on = [:x1, :x2, :x3])

How can I do this in a nice loop?

Thanks a lot!
