Takes the results from BA.est, DA.reg, AltReg or MCmcmc and returns a MethComp object, suitable for displaying the relationship between methods in print pr graphic form.

1	MethComp(obj)

obj

A MethComp or MCmcmc object.

Using MethComp on the results from BA.est or AltReg is not necessary, as these two functions already return objetcs of class MethComp.

MethComp returns a MethComp object, which is a list with three elements, Conv, a three-way array giving the linear conversion equations between methods, VarComp, a two-way array classified by methods and variance components and data, a copy of the original Meth object supplied — see the description under BA.est.

A MethComp object has an attribute Transform, which is either NULL, or a named list with elements trans and inv, both of which are functions. The first is the transformation applied to measurements before analysis; the results are all given on the transformed scale. The second is the inverse transformation; this is only used when plotting the resulting relationship between methods.

The methods print, plot, lines and points return nothing.
