Hello all,
I'm getting much further with my time-series work, but still getting
into some problems.
I'm using POSIXct time format with both date and time.
I'd like to use that in an its object but It seems its only processes
the date part of the POSIX time stamps:
BMU_its_data <- its(data[BMUindex,2-4],dates=data[BMUindex,1])
Error in `row.names<-.data.frame`(`*tmp*`, value = c("2007-10-31",
"2007-10-31", :
The first column of the data is certainly correct, with both date and time:
> summary(data[BMUindex,1])
Min. 1st Qu.
Median
"2007-10-31 07:00:00 UTC" "2007-11-01 07:00:00 UTC" "2007-11-03 07:00:00
UTC"
Mean 3rd Qu.
Max.
"2007-11-02 21:44:12 UTC" "2007-11-04 07:00:00 UTC" "2007-11-05 08:00:00
UTC"
Perhaps the functions used in its are unable to see the time field. I
noticed that using unique() on the same data gives me only 6 different
values, one for each day, with the times ignored.
Is there any time format I can use in R (through its or zoo or fCalendar
or anything) that allows me to use tools such as unique() and so on and
have the times (not only dates) considered?
I've chosen its because it seems to have pretty good ts specific
plotting stuff in there, but I'd be willing to use anything that allows
me to work with my POSIX dates down to the second. (or even msec)
Thanks.
