Mean mean of column values. Or specifying a range of rowscolumns. I matrices in Julia are repersented by 2D arrays I 2 -4 82.

Column Matrices one column N rows and Row Matrices one row N columns. 9 3 4 3 4 ArrayInt64 2. You can also just access the dataframe as you would a big matrix.

To programmatically compose a column name you need hence to use the SymbolString constructor eg. 12 3 17 16 julia dropdims maximum A dims 2 3-element ArrayInt64 1. Mean to all columns.

Column names are Julia symbols. As mentioned the aggregate function can also be used to implement the strategy which takes in the same three arguments as the by function. Each fs should return a value or vector.
