Layer labels are useful to identify layer in the layer inspector. The layer label can be initially set at layer creation with the label argument.
Details
Note that the layer label is not a state of the layer itself, instead is information that is part of the layer collection (i.e. its parent widget).
Examples
if(interactive()){
p <- l_plot()
l1 <- l_layer_rectangle(p, x=0:1, y=0:1, label="a rectangle")
l_layer_getLabel(p, 'model')
l_layer_getLabel(p, l1)
}
