lmeLevel {lme4} | R Documentation

## Construct an lmeLevel object

### Description

Create an `lmeLevel` object from its components

### Usage

    lmeLevel(precision, groups, columns, modelMatrix)

### Arguments

`precision` | A `pdMat` object representing the relative precision matrix for the random effects. This argument is missing in calls to generate the `lmeLevel` for the fixed-effects terms and for the response.
`groups` | The grouping factor. This argument is missing in calls to generate the `lmeLevel` for the fixed-effects terms and for the response.
`columns` | integer vector: the columns in `modelMatrix` corresponding to this level of random or fixed effects.
`modelMatrix` | a model matrix: the `original` slot of the containing `reStruct` object

### Details

An `lmeLevel` object contains information on one level of random-effects terms or the fixed-effects terms or the response in a linear mixed-effects structure.

### Value

An `lmeLevel` object.
