Check if an argument is equal to a given set

check_set_equal(x, y, ordered = FALSE, fmatch = FALSE)

  x,
  y,

)

Arguments

x

[any]
Object to check.

y

[atomic]
Set to compare with.

ordered

[logical(1)]
Check x to have the same length and order as y, i.e. check using “==” while handling NAs nicely. Default is FALSE.

fmatch

[logical(1)]
Use the set operations implemented in fmatch in package fastmatch. If fastmatch is not installed, this silently falls back to match. fmatch modifies y by reference: A hash table is added as attribute which is used in subsequent calls.

.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 assertSubset/assert_subset return x invisibly, whereas checkSubset/check_subset and testSubset/test_subset return TRUE. If the check is not successful, assertSubset/assert_subset throws an error message, testSubset/test_subset returns FALSE, and checkSubset returns a string with the error message. The function expect_subset always returns an expectation.

Note

The object x must be of the same type as the set w.r.t. typeof. Integers and doubles are both treated as numeric.
