expandEdits

edit expression, can be a <code>character</code> or <code>expression</code> vector

prefix for variables to be expanded

prefix

if <code>TRUE</code> sum expressions will be expanded

useSum

if <code>TRUE</code> an <code><a rd-options="" href="/link/expression?package=editrules&version=2.9.3" data-mini-rdoc="editrules::expression">expression</a></code> will be returned in stead of a <code>character</code>

asExpression

enviroment that will be used to find variables to be expanded

Often many numeric variables have the same constraints. <code>expandEdits</code> is
a utility function to define edits for multiple variables. See the examples for the syntax.

internal

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.
