I tried your new lines with some random time, it seems to be working
perfectly well, just as follows:
> z <- strptime("20/2/06 23:16:16.683", "%d/%m/%y %H:%M:%OS")
> modifyList(z, list(hour = z$hour + 11))
[1] "2006-02-21 10:16:16"
Now it seems that I have some problem with my Time vector. As Time was
created by the following code:
Time <- paste(anz$Date.G.,anz$Time.G.)
The original data looks like the following with each row correspond to each.
Date.G.
01-DEC-2008
01-DEC-2008
02-DEC-2008
03-DEC-2008
04-DEC-2008
...
Time.G.
00:03:57.398
00:04:03.778
00:04:38.639
00:04:38.639
00:04:38.639
...
Somehow, I can't read Time in strptime(Time,"%d-%b-%Y %H:%M:%OS"). Do you
know what was wrong with it?
Sorry for asking such questions, as I am quite new to R. Thanks for helping
me out.
