Dear fellow R-help members,
If my data is
YYYY MM DD HH
2015 04 24 01
2015 04 24 02
2015 04 24 06
Where
YYYY: year
MM:month
DD:day
HH: hour
How could I calculate the mean of the ISOdatetime(YYYY,MM,DD,HH,0,0) of
these?
With the mean() method? On my machine:
R> mean(ISOdatetime(YYYY,MM,DD,HH,0,0))
[1] "2015-04-24 03:00:00 CEST"
hth,
Z
Note: I set minutes and seconds to 0, as I don't have data for them.
?Thank you in advance!?
