R's help system is great, and I love that almost all help pages for a function include an example, but sometimes I wish there was a way to see the results of the example code without copying and pasting into my current session. This goes doubly for graphic functions.
Is there a way to do one of the following;

Some values in python can be modified, and some cannot. This does not ever mean that we can't change the value of a variable – but if a variable contains a value of an immutable type, we can only assign it a new value. We cannot alter the existing value in any way.
Module docstrings are placed at the top of the file even before any imports. Module docstrings should include the following: A brief description of the module and its purpose. A list of any classes, exception, functions, and any other objects exported by the module.
A Foolish Consistency is the Hobgoblin of Little Minds One of Guido's key insights is that code is read much more often than it is written. The guidelines provided here are intended to improve the readability of code and make it consistent across the wide spectrum of Python code.
PEP 8, sometimes spelled PEP8 or PEP-8, is a document that provides guidelines and best practices on how to write Python code. It was written in 2001 by Guido van Rossum, Barry Warsaw, and Nick Coghlan. The primary focus of PEP 8 is to improve the readability and consistency of Python code.
example(foo) is the usual interface to function foo. It will echo the example code to the console a line/chunk at a time, and pause between plots.
R's help system will soon be more fully dynamic, but this will only (IIRC) help matters if the package author rewrites all or parts of the man pages to include dynamic content. I'm not aware of a proposal to include output from examples in the new dynamic help, but it could potentially be done. If you have the standard R toolchain installed, you could grab package sources and check them - that creates an R file with the concatenated example code used for checking that the examples work.
(2) is getting a bit close to a vignette.

Use example, eg:
example(hist)
Or see the R Graphical Manual.
