nobars {lme4} | R Documentation |

## Omit terms separated by vertical bars in a formula

### Description

Remove the random-effects terms from a mixed-effects formula, thereby producing the fixed-effects formula.

### Usage

```
nobars(term)
```

### Arguments

`term` |
the right-hand side of a mixed-model formula |

### Value

the fixed-effects part of the formula

### Note

This function is called recursively on individual terms
in the model, which is why the argument is called
`term`

and not a name like `form`

, indicating a
formula.
