Description

Check that an argument is a vector of type double

Arguments

x

[any]
Object to check.
lower

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

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

[logical(1)]
Check for only finite values? Default is FALSE.
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.
sorted

[logical(1)]
Elements must be sorted in ascending order. Missing values are ignored.
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 assertDouble/assert_double return x invisibly, whereas checkDouble/check_double and testDouble/test_double return TRUE. If the check is not successful, assertDouble/assert_double throws an error message, testDouble/test_double returns FALSE, and checkDouble returns a string with the error message. The function expect_double always returns an expectation.
