add_listener

callback

<p>Plumbr data structures send only single event for data
  changes: data_changed.  This has a two arguments, i and
  j.  Either both are NULL, indicating a change in the
  shape of the underlying data, or they give the the
  locations of changed data values.</p>

The base R data.frame, like any vector, is
copied upon modification. This behavior is at odds with
that of GUIs and interactive graphics. To rectify this,
plumbr provides a mutable, dynamic tabular data model.
Models may be chained together to form the complex
plumbing necessary for sophisticated graphical
interfaces. Also included is a
general framework for linking datasets; an typical
use case would be a linked brush.
