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.
l_layer_getLabel(widget, layer)
widget | widget path or layer object of class |
---|---|
layer | layer id. If the widget argument is of class |
Named vector of length 1 with layer label as value and layer id as name.
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).
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) }
