| vpPath {grid} | R Documentation |
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.
vpPath(...)

Character values which are viewport names. |
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.
