I'm currently working my way through the adehabitatLT package. I've put my date_time column into characters and named it da:
da<-as.character(dat$date_time)
head(da)
[1] "7/08/2015 0:22" "7/08/2015 0:52" "7/08/2015 1:22" "7/08/2015 1:52" "7/08/2015 2:56" "7/08/2015 3:26"
As you can see my date_time input is a bit non traditional and i think this is where the error occurs, because when i create the class POSIXct:
da<-as.POSIXct(strptime(as.character(dat$date_time),"%d/%m/%y% H:%M:%S"))
It creates the class but i get NA for all my values:
head(da) [1] NA NA NA NA NA NA
My end objective here is to create an object of the class ltraj (but not only containing the date but the time as well).
Any ideas anyone?
Kind regards,
Sam
da<-as.POSIXct(strptime(as.character(locs$Date),"%y%m%d"))
While parsing tricky date/time formats, it might be useful to use lubridate package by Garrett Grolemund and Hadley Wickham.
In your case, simply do
require(lubridate)
a <- dmy_hm(da)
The separator and the number of digits for day or month or hours etc are automatically parsed.
