Hi Guys,
I'm cooking up my time series code. I want a data frame with first column as
timestamp in POSIXlt format.
I hit on this the problem of how to create an array/list/vector of POSIXlt
objects. Code is as follows
> dtt=array(dim = 2)
> t=as.POSIXlt( strptime("07/12/07 13:20:01", "%m/%d/%Y %H:%M:%S",tz="GMT"))
> dtt
[1] NA NA
> t
[1] "0007-07-12 13:20:01 GMT"
> dtt[1]=t
Warning message:
In dtt[1] = t :
number of items to replace is not a multiple of replacement length
> class(dtt)
[1] "list"
> class(t)
[1] "POSIXt" "POSIXlt"
> unclass(t)
$sec
[1] 1
$min
[1] 20
$hour
[1] 13
$mday
[1] 12
$mon
[1] 6
$year
[1] -1893
$wday
[1] 4
$yday
[1] 192
$isdst
[1] 0
attr(,"tzone")
[1] "GMT"
Seems like POSIXlt is matrix in this case.
Any suggestions?
Cheers,
B
