I create a zooreg object that runs from Jan-1-2002 0:00 to Jun-1-2005 0:00...
regts.start = ISOdatetime(2002, 1, 1, hour=0, min=0, sec=0, tz="") regts.end = ISOdatetime(2005, 6, 1, hour=0, min=0, sec=0, tz="") regts.zoo <- zooreg( NA, regts.start, regts.end, deltat=3600 ) Upon inspection: > regts.zoo[1:3] 2002-01-01 00:00:00 2002-01-01 01:00:00 2002-01-01 02:00:00 NA NA NA > regts.zoo[29926:29928] 2005-05-31 22:00:00 2005-05-31 23:00:00 2005-06-01 00:00:00 NA NA NA However: > summary(regts.zoo) Error in "row.names<-.data.frame"(`*tmp*`, value = c("2002-01-01 00:00:00", : duplicate 'row.names' are not allowed I don't understand why it claims that there are duplicate row.names. Any advice? I probably could use the aggregate function to clean this up, but I don't see why it should be needed (provided that I do things properly in the first place).
