loon (version 1.4.1)

l_layer_group: layer a group node

Description

Loon's displays that are based on Cartesian coordinates (i.e. scatterplot, histogram and graph display) allow for layering visual information including polygons, text and rectangles.

A group layer can contain other layers. If the group layer is invisible, then so are all its children.

Usage

l_layer_group(widget, label = "group", parent = "root", index = 0)

Value

layer object handle, layer id

Arguments

widget

widget path name as a string

label

label used in the layers inspector

parent

group layer

index

of the newly added layer in its parent group
