Hello,
The format AM/PM should be for display purposes only, when you use
format() you get a variable of class character, not of classes
POSIXct POSIXt . Produce a variable y with as.POSIXct (without
AM/PM) for arithmetics and another formated for display.
Hope this helps,
Rui Barradas

Hello all,
Let say I have following (numeric) vector:
x
[1] 11.00 11.25 11.35 12.01 11.14 13.00 13.25 13.35 14.01 13.14 14.50
14.75 14.85 15.51 14.64
Now, I want to create a 'Date' variable (i.e. I should be able to do all
calculations pertaining to date/time and also time-series plotting
Hello,
Try the following.
x - scan(text = 11.00 11.25 11.35 12.01 11.14 13.00 13.25 13.35 14.01
13.14 14.50 14.75 14.85 15.51 14.64 )
hours - floor(x)
mins - (100*x) %% 100
as.POSIXct(paste(Sys.Date(), hours, mins), format = %Y-%m-%d %H %M)
As you can see, there are three values of 'x'
