## Tilde Operator

### Description

Tilde is used to separate the left- and right-hand sides in a model formula.

### Usage

```
y ~ model
```

### Arguments

`y` , `model` |
symbolic expressions. |

### Details

The left-hand side is optional, and one-sided formulae are used in some contexts.

A formula has mode `call`

. It can be subsetted by
`[[`

: the components are `~`

, the left-hand side (if
present) and the right-hand side *in that order*. (Thus
one-sided formulae have two components.)
