Operators on the Date Class

Operators for the "Date" class.

There is an Ops method and specific methods for + and - for the Date class.

date + x
x + date
date - x
date1 lop date2

date

an object of class "Date".

date1, date2

date objects or character vectors. (Character vectors are converted by as.Date.)

x

a numeric vector (in days) or an object of class "difftime", rounded to the nearest whole day.

lop

one of ==, !=, <, <=, > or >=.

x does not need to be integer if specified as a numeric vector, but see the comments about fractional days in the help for Dates.

z + 10
z < c("2009-06-01", "2010-01-01", "2015-01-01")
