Arguments

x

[any]
Object to check.

lower

[Date]
All non-missing dates in x must be >= this date. Comparison is done via Ops.Date.

upper

[Date]
All non-missing 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 no non-missing values allowed? Default is TRUE. Note that empty vectors do not have non-missing values.

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.

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.

Value

Depending on the function prefix: If the check is successful, the functions assertAtomic/assert_atomic return x invisibly, whereas checkAtomic/check_atomic and testAtomic/test_atomic return TRUE. If the check is not successful, assertAtomic/assert_atomic throws an error message, testAtomic/test_atomic returns FALSE, and checkAtomic/check_atomic return a string with the error message. The function expect_atomic always returns an expectation.
