[R] Odp: number of days

[Petr PIKAL]

Hi

it will partly depend on which format of dates you use but usually it is 
as easy as

> dates <- c("02/27/92", "02/27/92", "01/14/92", "02/28/92", "02/01/92")
> ddd<-as.Date(dates, "%m/%d/%y")
> diff(ddd)
Time differences in days
[1]   0 -44  45 -27
> Sys.Date()-ddd
Time differences in days
[1] 5555 5555 5599 5554 5581

Regards
