Another way is
t1<- c("3:00","1:59","3:00","2:00")
t2 <- strptime(t1, format="%H:%M")
t2[-4]>t2[-1]

Hi guys,
I have a large text file with a bunch of Time in "HH:MM" format,
what would
be the best way to process it into a Time Object so that I can use
comparisons like (1:00<"1:15") or (13:00>"2:00") to both return true.
Right now if I do a comparison like (3:00 < "1:59") I get a true,
but if I
do (3:00 < "2:00") I get false, which is an obvious error.
Try this:
library(chron)
t1 <- times(paste("13:00", "00", sep = ":"))
t2 <- times(paste("2:00", "00", sep = ":"))
t1 > t2
