[R] Question on creating Date variable

[Rui Barradas]

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' with decimal part greater 
than 60, which will give mins > 60 and therefore NA date/times.


Hope this helps,

Rui Barradas
