The MxConstraint class has the following slots: rcl{
name - The name of the object
formula - The R expression to be evaluated
}
The name slot is the name of the MxConstraint object. Use of MxConstraint objects in other functions in the OpenMx library may require reference by name.
The formula slot is an expression containing the expression to be evaluated. These objects are operated on or related to one another using one or more operations detailed in the mxConstraint help file.
Slots may be referenced with the $ symbol. See the documentation for Classes and the examples in the mxConstraint document for more information.
