## A function to build the covariate matrix of the constraints

### Description

A function to build the covariate matrix of the constraints

### Usage

    buildCovMat(datFrame)

### Arguments

`datFrame` | the dataframe with which the covariate matrix is to be built In this case we will 1) Include dummy's for every level of the categorical variable, and force them to sum to zero. This is needed for plotting and required for reference level indepenent normalization. 2) Exclude an intercept. The density function f() will provide this already.

### Value

a list with components

`covModelMat` | The model matrix
`datFrame` | The dataframe used to construct the model matrix
