Hello,
To compute the difference between two date/time objects use the minus

?difftime
?`-.POSIXt`
Hope this helps,

Dear sir/madam,
I used as.Date,strptime, POXIct, and POXIlt functions to
work on my data in R. Please, I would like to know the function to find the
difference between the dates and times in two different columns and make a new
column for that. Thank you
