## Creates an object for calculating Omega/Omega^-1 and derivatives

### Description

Creates an object for calculating Omega/Omega^-1 and derivatives

### Usage

      create.env = TRUE, envir = parent.frame())

### Arguments

`mat` | Initial Omega matrix
`diag.xform` | transformation to diagonal elements of OMEGA. or `chol(Omega^-1)`
`create.env` | – Create an environment to calculate the inverses. (By default TRUE)
`envir` | – Environment to evaluate function, bu default it is the parent frame.
