Hi, is there a function to apply a function to each value in specific column of a DataFrame, and then return a DataFrame with the new column replacing the old column even if it has a different eltype? Something like
mutate(df, col, my_function_that_operates_on_each_val_of_col)
For example, starting with
DataFrame(a = 1:3, b = ["2019 January", "2020 December", "2014 July"])
and using a function I made that operates on a single string to go to
DataFrame(a = 1:3, b = [Date(2019-01-01), Date(2020-12-01), Date(2014-07-01)])
I’d also be fine with a function that operates on a column and just adds the new column to the dataframe so I can drop the old column manually, if it’s not possible to change the datatype of an existing column.
