## Linear Mixed-Effects Structure

### Description

A linear mixed-effects structure is a list of model components
representing different sets of parameters in the linear mixed-effects
model. An `lmeStruct`

list must contain at least a
`reStruct`

object, but may also contain `corStruct`

and
`varFunc`

objects. `NULL`

arguments are not included in the
`lmeStruct`

list.

### Usage

lmeStruct(reStruct, corStruct, varStruct)

### Arguments

`reStruct` |
a `reStruct` representing a random effects
structure. |

`corStruct` |
an optional `corStruct` object, representing a
correlation structure. Default is `NULL` . |

`varStruct` |
an optional `varFunc` object, representing a
variance function structure. Default is `NULL` . |

### Value

a list of model components determining the parameters to be estimated
for the associated linear mixed-effects model.
