R help - May 2013 - Hello

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

Hello,

To compute the difference between two date/time objects use the minus 
operator. See

?difftime
?`-.POSIXt`


Hope this helps,

Rui Barradas
