[R] Condition warning: has length 1 and only the first element will be used

Hello, I've been learning R functions recently and I've come across a problem that perhaps someone could help me with. # I have a a chron() object of times hours=chron(time=c(01:00:00,18:00:00,13:00:00,10:00:00)) # I would like to subtract 12 hours from each time element, so I created a
