Hi all,
I'm using chron and it seems to me that there is a strange behaviour
when constructing chronological objects.
An extract of my source data is:
> tdr.hhmm[4860:4870]
[1] "22:22:00" "22:42:00" "23:02:00"
"23:22:00" "23:42:00" "00:02:00"
[7] "00:22:00" "00:42:00" "01:02:00"
"01:22:00" "01:42:00"> tdr.dat$year[4860:4870]
[1] 2005 2005 2005 2005 2005 2006 2006 2006 2006 2006
2006> tdr.dat$day[4860:4870]
[1] 365 365 365 365 365 1 1 1 1 1 1
And if I use:> tdr.chron <-
chron(dates.=tdr.dat$day,times.=tdr.hhmm,origin.=c(month=1,day=0,year=tdr.dat$year),format=c(dates="d/m/y",times="h:m:s"))
The result is:
> tdr.chron[4860:4870]
[1] (31/12/05 22:22:00) (31/12/05 22:42:00) (31/12/05 23:02:00)
[4] (31/12/05 23:22:00) (31/12/05 23:42:00) (01/01/05 00:02:00)
[7] (01/01/05 00:22:00) (01/01/05 00:42:00) (01/01/05 01:02:00)
[10] (01/01/05 01:22:00) (01/01/05 01:42:00)
While it seems to me that, through the R recycling rule, it should
consider the year 2006 in the corresponding results. Isn't it so?
Wishes,
Javier
