buildCovMat: A function to build the covariate matrix of the constraints

In combi: Compositional omics model based visual integration

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
