Remove an object from a model
You can remove paths, matrices, algebras, and other objects from a model using mxModel, with the to-be-modified model as its first parameter, and then a comma delimited list of the names of the objects you want to remove, setting remove to TRUE
e.g.aModel mxModel("aModel", mxMatrix(name="myMatrix", type="Full",nrow=8,ncol=5)) aMinus mxModel(aModel, "myMatrix", remove = TRUE)
Here is an example why you must use the name of the entity instead of the entity itself. The following code WILL NOT WORK and is not allowed to work because "container.A" and "submodel.A" are identical objects. Both objects contain the value "A" in the slot "name."A # Oh oh, this would have deleted "countainer.A" instead of "submodel.A" accident
