The length() of a POSIXlt object is given as 9 regardless of the actual
length. For example:
make.date.time
function (year=c(2006,2006),month=c(8,8),day=2:5,hour=13,minute=45)
{# convert year, etc., into POSIXlt object
#
d=as.character(make.date(year,month,day))
t=paste(hour,minute,sep=":")
as.POSIXlt(paste(d,t))
}
t=make.date.time()
t
[1] "2006-08-02 13:45:00" "2006-08-03 13:45:00" "2006-08-04 13:45:00"
[4] "2006-08-05 13:45:00"
length(t)
[1] 9
t[1]
[1] "2006-08-02 13:45:00"
length(t[1])
[1] 9
