Obvious contradictions are edits of the form \(1 &lt; 0\), or categorical
edits defining that a record fails for any value combination If
this function evaluates to <code>TRUE</code>, the set of edits is guaranteed
infeasible. If it evaluates to <code>FALSE</code> this does not garuantee feasibility.
See <code>isFeasible</code> for a complete test.

Please note: active development has moved to packages 'validate'
and 'errorlocate'. Facilitates reading and manipulating (multivariate) data
restrictions (edit rules) on numerical and categorical data. Rules can be
defined with common R syntax and parsed to an internal (matrix-like format).
Rules can be manipulated with variable elimination and value substitution
methods, allowing for feasibility checks and more. Data can be tested against
the rules and erroneous fields can be found based on Fellegi and Holt's
generalized principle. Rules dependencies can be visualized with using the
'igraph' package.
