dob: Generate Random Vector of Birth Dates

Description

Generate a random vector of birth dates.

Usage

dob(
  n,
  random = TRUE,
  x = NULL,
  start = Sys.Date() - 365 * 15,
  k = 365 * 2,
  by = "1 days",
  prob = NULL,
  name = "DOB"
)

birth( n, random = TRUE, x = NULL, start = Sys.Date() - 365 * 15, k = 365 * 2, by = "1 days", prob = NULL, name = "Birth" )

Arguments

n

The number elements to generate. This can be globally set within the environment of r_data_frame or r_list.

random

logical. If TRUE the dates are randomized, otherwise the dates are sequential.

x

A vector of elements to chose from. This may be NULL if arguments are supplied to start, k, and by. The x argument takes precedence over the other three if !is.null. Note that start, k, and by work together to make a vector of dates to sample from. See seq.Date for additional information.

start

A date to start the sequence at.

k

The length of the sequence (number of the elements) so build out from start.

by

The interval to use in building the sequence.

prob

A vector of probabilities to chose from.

name

The name to assign to the output vector's varname attribute. This is used to auto assign names to the column/vector name when used inside of r_data_frame or r_list.

Value

Returns a random vector of birth date elements.
