R Documentation

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.
