Hi All,, I am new to R and having a problem dealing with timestamps. I have 2 columns in my table . Both of these have timestamps value in format 06/22/11 05:34 PM .
If these are Date or DateTime objects you can use: ?difftime # with attention to the units argument ?DateTimeClasses If they are not yet in a correct class you need to first use: ?strptime
I want to calculate the difference in these 2 columns ( in minutes) and save it as a 3rd column.
