grid.get: Get a Grid Graphical Object

grid.get

R Documentation

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`.

Details

grid.gget (g for global) is just a convenience wrapper for grid.get with different defaults.

Value

A grob object.
