grid (version 3.4.3)

vpPath: 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.

Value

A vpPath object.

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.
