Objects used for collecting Cocktail definitions.
These objects work as expert systems for recognition of defined
vegetation units among plots of a vegtable object.
A shaker
object will be always dependent on a vegtable object,
which is called companion
.
Since modifications in the companion
may affect the functionality of
the shaker
object, it will be recommended to create the last during
a session by a source script instead of recycling them from old R images.
