Dear R experts, I have a question about the result of difftime() function: Does it take into account the different number of days in each month. In my example, I have the following:
> firstDay [1] "2010-02-20" > lastDay [1] "2010-05-20 16:00:00" > difftime(lastDay,firstDay,units='days') Time difference of 89.625 days > When I count the days I get 88 days from 20/02/2010 to 20/05/2010 consequently the difference in days should be 87. On the contrary, difftime gives a higher number, so I doubt whether it takes into account the fact that february has 28 days (or 29). Could you please help? Thank you very much in advance.
