[R] R difftime function: How can we fix the difftime unit?
Hi, I am trying to take difference of two time objects. I want to fix the result's unit to minutes. How can I do that? Here is an example:> difftime(x, y)Time difference of 2.030720 hours> difftime(x, z)Time difference of 30.34672 mins where x = '2007-03-05 08:32:58' y = '2007-03-05 06:31:07' and z = '2007-03-05 08:02:37' How can I get answer something like for (x-y) Time difference of 121.8432 mins and for (x-z) Time difference of 30.34672 mins Kindly help. -- Thanks & Regards Sarthi M.

That's easy: difftime(x, y, units = "min") Best regards Frede ________________________________ Fra: r-help-bounces at stat.math.ethz.ch p? vegne af d. sarthi maheshwari Sendt: to 22-03-2007 07:03 Til: r-help at stat.math.ethz.ch Emne: [R] R difftime function: How can we fix the difftime unit?
