I have a data frame where the year, month, day, hour, etc. are in different columns. I want to use Datetime.jl to make timestamps, then do some processing.
I tried to attack the problem like the following (which is to say, Python-style), but it didn't work: test[:start_date] = [datetime(year,month,day) for year,month,day in zip(test[:Year], test[:Month], test[:DayofMonth])] The working solution: test[:start_date] = [datetime(value[1],value[2],value[3]) for value in zip(test[:Year], test[:Month], test[:DayofMonth])] I was somewhat surprised that I had to reference the fields in the tuple by position, when syntax like a,b,c = (1,2,3) works elsewhere. Is there something I'm missing/forgetting? Is there a better way to use multiple columns from a data frame in a function to return a new column in the data frame?
