Sorry for the newbie question. I want to do a hcat with a dataframe and an array, such that the column name is the name of the vector (rather than the default ‘X1’): df = DataFrame(A = 1:4, B = [2,4,3,5 ]) newCol = [7,8,9,2] newdf = hcat(df,newCol) 4×3 DataFrame │ Row │ A │ B │ x1 │ │ …

DataFrames: hcat

instead of hcat, to add a new column, df.blah = newCol will do
