Create and Apply Edit Objects

The functions gEdit and gEditList create objects representing an edit operation (essentially a list of arguments to editGrob).

The functions applyEdit and applyEdits apply one or more edit operations to a graphical object.

These functions are most useful for developers creating new graphical functions and objects.

gEdit(...)
gEditList(...)
applyEdit(x, edit)
applyEdits(x, edits)

`...`	one or more arguments to the `editGrob` function (for `gEdit`) or one or more `"gEdit"` objects (for `gEditList`).
`x`	a grob (grid graphical object).
`edit`	a `"gEdit"` object.
`edits`	either a `"gEdit"` object or a `"gEditList"` object.

gEdit returns an object of class "gEdit".

gEditList returns an object of class "gEditList".

applyEdit and applyEditList return the modified grob.

grid.rect(gp=gpar(col="red"))
# same thing, but more verbose
grid.draw(applyEdit(rectGrob(), gEdit(gp=gpar(col="red"))))
