Specifies a Layer within a Graphic. Each Layer in the
Grammar of Graphics framework contains a Stat, a Geom, and
a Position. The data_src and ColumnMapping are used to create
the data for each layer; the stat_mapping is a ColumnMapping that
is applied after the Stat is computed.
new()Layer$new( data_src = NULL, mapping = ColumnMappingIdentity$new(data_src), stat_mapping = ColumnMappingIdentity$new(), geom = GeomBlank$new(), stat = StatIdentity$new(), position = PositionIdentity$new() )
data()Layer$data(data_src)
data_stat()Layer$data_stat(data_stat)
clone()The objects of this class are cloneable with this method.
Layer$clone(deep = FALSE)
deepWhether to make a deep clone.
