Check Set Ordered
Checks if the first occurrence of each shared element
in x is equivalent to the first occurrence of each shared element in values using
vld_equivalent(unique(x[x %in% values]), values[values %in% x]).
chk_orderset(x, values, x_name = NULL)
x |
The object to check. |
values |
A vector of the permitted values. |
x_name |
A string of the name of object x or NULL. |
The chk_ function throws an informative error if the test fails.
The vld_ function returns a flag indicating whether the test was met.
