predicate: Predicate functions

In mdlincoln/dateSampler: Generate Randomized Dates

Description

Predicate functions must take a year, month, and day integer as its parameters, and return TRUE if the date is valid. Allows one to construct complex date restrictions, such as only generating dates that are Mondays, etc.

Usage

is_monday(y, m, d)

null_predicate(y, m, d)

Arguments

y	Integer. Candidate year.
m	Integer. Candidate month.
d	Integer. Candidate day.

Value

TRUE if the date is valid, and FALSE if it is not and should be resampled.

Functions

• is_monday: An example predicate function that can be passed to sample_date so that it will return only those dates that fall on Mondays.

• null_predicate: Always returns TRUE. This is the default predicate used by sample_date. Used when initially checking values so that the supplied predicate never rejects a starting condition out-of-hand.
