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.
