To clarify, here is a sample code (rpy is a Python interface to R):

def Test [html] ():To clarify, here is a sample code (rpy is a Python
interface to R):

def Test [html] ():
      import rpy
      rpy.r.png(file=str("test.png")
      rpy.r.plot(rpy.r.norm(100))
      rpy.r.dev_off()
      # rest of code ...

When I call this function, there is a line

{'null device': 1}

displayed on the webpage.

This result is similar to the result of a console R session.

null device

Putting """<--""" before the import and """-->""" after  the rpy block
(specifically the line rpy.r.dev_off()) will prevent making a mess of
the html display.  But any lines such as {'null device': 1} will still
be be on the html page source.  I was wondering if there was
something like ptl_off() and ptl_on() available.
