id(n, random = FALSE, name = "ID")

id_factor(n, random = FALSE, name = "ID")

`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 IDs are randomized, otherwise the IDs are sequential.
`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`.

Returns a (optionally random) vector of character/factor observations ID numbers.

id uses sprintf to generate the padded ID. Per sprintf's documentation: “The format string is passed down the OS's sprintf function...The behaviour on inputs not documented here is 'undefined', which means it is allowed to differ by platform.” See sprintf for details.

id is faster than id_factor, as the later coerces the vector to a factor.
