vpPath {grid} | R Documentation

## Concatenate Viewport Names

### Description

This function can be used to generate a viewport path for use in `downViewport` or `seekViewport`.

A viewport path is a list of nested viewport names.

### Usage

    vpPath(...)

### Arguments

`...` | Character values which are viewport names.

### Details

Viewport names must only be unique amongst viewports which share the same parent in the viewport tree.

This function can be used to generate a specification for a viewport that includes the viewport's parent's name (and the name of its parent and so on).

For interactive use, it is possible to directly specify a path, but it is strongly recommended that this function is used otherwise in case the path separator is changed in future versions of grid.

### Value

A `vpPath` object.

### See Also

`viewport`, `pushViewport`, `popViewport`, `downViewport`, `seekViewport`, `upViewport`

### Examples

    vpPath("vp1", "vp2")
