(7 replies) a data set like this: year month day count 2001 1 1 10 2001 1 2 11. 2004 7 17 8. basically it is a count of of some numbers everyday through a few years now I'd like to get the mean of the count for every day. I thought I can do this using for and ifelse, but is there a simple way to do this? I wish a function like mean...
