Calculate monthly means
I am trying to calculate monthly means by year of phosphates and nitrates from a multi year data set. Can anybody help me out with the most effective way to do this?
My data looks like this:
Collection_Date Test.Name Value
2000-01-24 17:00:00 Phosphate 0.108
2000-01-24 17:00:00 Nitrate 0.037
2001-11-12
