Calculate time between UTC in R

Question

So I have a series of values in two columns in this format

6/14/1998 17:30 | 6/16/1998 1:45

I would like to calculate the time between this two timestamps in R.

Basically, calculate the number of hours between t1 and t2. Could you please help?

Thanks!

Answer 1

Elementary, and covered a million times:

R> difftime(strptime("6/16/1998 01:45", "%m/%d/%Y %H:%M", tz="UTC"),
+           strptime("6/14/1998 17:30", "%m/%d/%Y %H:%M", tz="UTC"),
+           unit="min")     
Time difference of 1935 mins
R> 

See help(difftime) and help(strptime).
