Hello
I am trying to read a date and time from a file and convert them to POSIXct
using strptime()
the dates are stored in t which is a factor
This the code I am using to illustarte
> t[1]
[1] 07/14/2009 13:41:00
10 Levels: 07/14/2009 13:41:00 07/14/2009 13:42:00 ... 07/15/2009 07:12:00
> a=t[1]
> a
[1] 07/14/2009 13:41:00
10 Levels: 07/14/2009 13:41:00 07/14/2009 13:42:00 ... 07/15/2009 07:12:00
> a=t[[1]]
> a
[1] 07/14/2009 13:41:00
10 Levels: 07/14/2009 13:41:00 07/14/2009 13:42:00 ... 07/15/2009 07:12:00
> as.character(a)
[1] "07/14/2009 13:41:00"
> z=strptime(a,"%m/%d/%y %H:%M")
> z
[1] NA
> z=strptime("07/14/2009 13:41:00","%m/%d/%y %H:%M")
> z
[1] NA
Why do I get NA?
I am running R 2.8, openSUSE 11.0
Thanks
