Hello
I have a variable dailyHDD=(1x365) which represents the daily temperature for each day of the year. I am trying to calculate the total for each month and I am not sure sure to do it, In this column 1-31 will be january month. please can you assist on how to break this into 12 months and calculate the total for each month.
Regards
Farai

....You say the 'total' for each month as if you want the sum. Your situation however makes it sound more practical to have the mean.
Do you really want the sum?
