checkDate: Check that an argument is a Date

Description

Checks that an object is of class Date.

Usage

checkDate(x, lower = NULL, upper = NULL, any.missing = TRUE,
  all.missing = TRUE, len = NULL, min.len = NULL, max.len = NULL,
  unique = FALSE)
assertDate(x, lower = NULL, upper = NULL, any.missing = TRUE,
  all.missing = TRUE, len = NULL, min.len = NULL, max.len = NULL,
  unique = FALSE, add = NULL, .var.name = NULL)
assert_date(x, lower = NULL, upper = NULL, any.missing = TRUE,
  all.missing = TRUE, len = NULL, min.len = NULL, max.len = NULL,
  unique = FALSE, add = NULL, .var.name = NULL)
testDate(x, lower = NULL, upper = NULL, any.missing = TRUE,
  all.missing = TRUE, len = NULL, min.len = NULL, max.len = NULL,
  unique = FALSE)
test_date(x, lower = NULL, upper = NULL, any.missing = TRUE,
  all.missing = TRUE, len = NULL, min.len = NULL, max.len = NULL,
  unique = FALSE)
expect_date(x, lower = NULL, upper = NULL, any.missing = TRUE,
  all.missing = TRUE, len = NULL, min.len = NULL, max.len = NULL,
  unique = FALSE, info = NULL, label = NULL)

Arguments

[any] Object to check.

lower

[Date] All dates in x must be after this date. Comparison is done via Ops.Date.

upper

[Date] All dates in x must be before this date. Comparison is done via Ops.Date.

any.missing

[logical(1)] Are vectors with missing values allowed? Default is TRUE.

all.missing

[logical(1)] Are vectors with only missing values allowed? Default is TRUE.

len

[integer(1)] Exact expected length of x.

min.len

[integer(1)] Minimal length of x.

max.len

[integer(1)] Maximal length of x.

unique

[logical(1)] Must all values be unique? Default is FALSE.

add

[AssertCollection] Collection to store assertions. See AssertCollection.

.var.name

[NULL || character(1)] Name of the checked object to print in error message. If NULL, the name will be heuristically determined via substitute.

info

[character(1)] Extra information to be included in the message for the testthat reporter. See expect_that.

label

[character(1)] Same as .var.name, but passed down to expect_that.

Value

Depending on the function prefix: If the check is successful, the functions return TRUE. If the check is not successful, assertAtmoic/assert_atmoic throws an error message, testAtmoic/test_atmoic returns FALSE, and checkAtmoic returns a string with the error message. The function expect_atmoic always returns an expectation.
