assertive.datetimes

A set of predicates and assertions for checking the properties of dates and times. Most of the documentation is on the assertive page. End-users will usually want to use assertive directly.

Installation

To install the stable version, type:

install.packages("assertive.datetimes")

To install the development version, you first need the devtools package.

install.packages("devtools")

Then you can install the assertive.datetimes package using

library(devtools)
install_bitbucket("richierocks/assertive.datetimes")

Predicates

is_date_string checks character vectors to see if they contain dates and times.

is_before, and is_after check whether Dates or POSIXt objects are before or after some time.

is_in_past and is_in_future are like the above, compared to the present time.

Assertions

All predicates return a vector and have two corresponding assertions. For example, is_after has assert_all_are_after and assert_any_are_after.
