Create a specified date stabilizer function

Source: R/specify_date.R
specify_date.Rd

specify_date() creates a function that will call stabilize_date() with the provided arguments. specify_date_scalar() creates a function that will call stabilize_date_scalar() with the provided arguments.

Usage

specify_date(
  allow_null = TRUE,
  allow_na = TRUE,
  min_size = NULL,
  max_size = NULL,
  unique = FALSE,
  min_value = NULL,
  max_value = NULL,
  allowed_values = NULL
)

specify_date_scalar(
  allow_null = FALSE,
  allow_zero_length = FALSE,
  allow_na = TRUE,
  min_value = NULL,
  max_value = NULL,
  allowed_values = NULL
)

Arguments

allow_null

(logical(1)) Is NULL an acceptable value?

allow_na

(logical(1)) Are NA values ok?

min_size

(integer(1)) The minimum size of the object. Object size will be tested using vctrs::vec_size().

max_size

(integer(1)) The maximum size of the object. Object size will be tested using vctrs::vec_size().

unique

(logical(1)) Should all elements in x be distinct?

min_value

(numeric(1)) The lowest allowed value for x. If NULL (default) values are not checked.

max_value

(numeric(1)) The highest allowed value for x. If NULL (default) values are not checked.

allowed_values

A vector of permitted values (coerced to the target type). NULL (default) skips the check. NA values in x are permitted independently of allowed_values, subject to allow_na.

allow_zero_length

(logical(1)) Are zero-length vectors acceptable?

Value

A function of class "stbl_specified_fn" that calls stabilize_date() or stabilize_date_scalar() with the provided arguments. The generated function will also accept ... for additional arguments to pass to stabilize_date() or stabilize_date_scalar(). You can copy/paste the body of the resulting function if you want to provide additional context or functionality.

Examples

stabilize_recent <- specify_date(min_value = "2000-01-01")
stabilize_recent("2024-01-01")
#> [1] "2024-01-01"
try(stabilize_recent("1999-12-31"))
#> Error in eval(expr, envir) : `"1999-12-31"` must be >= 2000-01-01.
#> ✖ "1999-12-31" is too low.
