grid.get: Get a Grid Graphical Object

Description

Retrieve a grob or a descendant of a grob.

Usage

grid.get(gPath, strict = FALSE, grep = FALSE, global = FALSE, allDevices = FALSE)
grid.gget(..., grep = TRUE, global = TRUE)
getGrob(gTree, gPath, strict = FALSE, grep = FALSE, global = FALSE)

Arguments

gTree

A gTree object.

gPath

A gPath object. For grid.get this specifies a grob on the display list. For getGrob this specifies a descendant of the specified gTree.

strict

A boolean indicating whether the gPath must be matched exactly.

grep

A boolean indicating whether the gPath should be treated as a regular expression. Values are recycled across elements of the gPath (e.g., c(TRUE, FALSE) means that every odd element of the gPath will be treated as a regular expression).

global

A boolean indicating whether the function should affect just the first match of the gPath, or whether all matches should be affected.

allDevices

A boolean indicating whether all open devices should be searched for matches, or just the current device. NOT YET IMPLEMENTED.

...

Arguments that are passed to grid.get.

Value

A grob object.
