[R] Subtracting number of days from a date

[Hoeven, Maarten van der]

Hi group,

suppose I have a date, say May 15 2004, and I want to now what date it is 23 days before that date. The way to calculate the new date should (...) take account of leap years :)


In pseudocode:

olddate <- "May 15 2004"
newdate <- olddate-23

I looked around in POSIXct etc..., maybe I overlooked?

Thanks,
Maarten
