# mkVarCorr: Make Variance and Correlation Matrices from `theta`

## Description

Make variance and correlation matrices from `theta`

## Usage

mkVarCorr(sc, cnms, nc, theta, nms)

## Arguments

- sc
scale factor (residual standard deviation).

- cnms
component names.

- nc
numeric vector: number of terms in each RE component.

- theta
theta vector (lower-triangle of Cholesky factors).

- nms
component names (FIXME: nms/cnms redundant:
nms=names(cnms)?)
