Arguments

x

[any]
Object to check.

lower

[numeric(1)]
Lower value all elements of x must be greater than.

upper

[numeric(1)]
Upper value all elements of x must be lower than.

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.

names

[character(1)]
Check for names. See checkNamed for possible values. Default is “any” which performs no check at all. Note that you can use checkSubset to check for a specific set of names.

null.ok

[logical(1)]
If set to TRUE, x may also be NULL. In this case only a type check of x is performed, all additional checks are disabled.

.var.name

[character(1)]
Name of the checked object to print in assertions. Defaults to the heuristic implemented in vname.

add

[AssertCollection]
Collection to store assertion messages. See AssertCollection.

info

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

label

[character(1)]
Name of the checked object to print in messages. Defaults to the heuristic implemented in vname.

Details

This function does not distinguish between NA, NA_integer_, NA_real_, NA_complex_ NA_character_ and NaN.

Value

Depending on the function prefix: If the check is successful, the functions assertInteger/assert_integer return x invisibly, whereas checkInteger/check_integer and testInteger/test_integer return TRUE. If the check is not successful, assertInteger/assert_integer throws an error message, testInteger/test_integer returns FALSE, and checkInteger returns a string with the error message. The function expect_integer always returns an expectation.
