Hello,
I'm very new to R, and so my question is simple.
I have data record with 80 years of daily temperatures in one long
string. The dates are also recorded, in YYMMDD format. I'd like to
learn an elegant simple way to pull out the annual averages.
(Obviously, every 4th year has 366 days.)
I know I can set up a formal loop to create annual records and then
average. But R seems to have such neat methods, is there some better
way to do this?
