Returns a proxy object (i.e. an atomic vector or data frame of atomic vectors). For vctrs, this determines the behaviour of == and != (via vec_equal()); unique(), duplicated() (via vec_unique() and vec_duplicate_detect()); and anyNA() (via vec_equal_na()).

vec_proxy_equal(x, ...)



A vector x.


These dots are for future extensions and must be empty.


A 1d atomic vector or a data frame.


The default method calls vec_proxy(), as the default underlying vector data should be equal-able in most cases. If your class is not equal-able, provide a vec_proxy_equal() method that throws an error.
