Hi there
I have precipitation data from 2004 to 2006 in varying resolutions (10 to 20min
intervals) with time in seconds from beginnig of the year (summation) and a
second variable as year.
I applied follwing code to convert the time into a date:
times<-strptime("2004-01-01", "%Y-%m-%d", tz="GMT") + precipitation$time1
everytihng went well, except that every year, the seconds-counter starts by
zero, therefore I have now three 2004 series instead of going further from 04
to 05 etc.
I tried to sum the last seconds-values of 2004 to the first of 2005 with an if
command like:
if (year=2005) time2=time1+632489 ;(seconds)
but it doesn't work.
thanks for a solution
marc
