check_set_equality()
is a wrapper of check_subset()
.
It tests if one value set is a subset of another and vice versa, i.e., if both sets are the same.
If not, it throws an error.
check_set_equality(t1, c1, t2, c2)
t1 |
The data frame that contains the columns |
c1 |
The columns of |
t2 |
The data frame that contains the columns |
c2 |
The columns of |
Returns t1
, invisibly, if the check is passed.
Otherwise an error is thrown and the reason for it is explained.
