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"))))
