checkRaw: Check if an argument is a raw vector

Description

Check if an argument is a raw vector

Usage

checkRaw(
  x,
  len = NULL,
  min.len = NULL,
  max.len = NULL,
  names = NULL,
  null.ok = FALSE
)

check_raw( x, len = NULL, min.len = NULL, max.len = NULL, names = NULL, null.ok = FALSE )

assertRaw( x, len = NULL, min.len = NULL, max.len = NULL, names = NULL, null.ok = FALSE, .var.name = vname(x), add = NULL )

assert_raw( x, len = NULL, min.len = NULL, max.len = NULL, names = NULL, null.ok = FALSE, .var.name = vname(x), add = NULL )

testRaw( x, len = NULL, min.len = NULL, max.len = NULL, names = NULL, null.ok = FALSE )

test_raw( x, len = NULL, min.len = NULL, max.len = NULL, names = NULL, null.ok = FALSE )

expect_raw( x, len = NULL, min.len = NULL, max.len = NULL, names = NULL, null.ok = FALSE, info = NULL, label = vname(x) )

Value

Depending on the function prefix: If the check is successful, the functions

assertRaw/assert_raw return

x invisibly, whereas

checkRaw/check_raw and

testRaw/test_raw return

TRUE. If the check is not successful,

assertRaw/assert_raw

throws an error message,

testRaw/test_raw

returns FALSE, and checkRaw/check_raw

return a string with the error message. The function expect_raw always returns an

expectation.

Arguments

x

[any]
Object to check.

len

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

min.len

[integer(1)]
Minimal length of x.

max.len

[integer(1)]
Maximal length of x.

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.
