[R] attaching data to any object

[Patrick Burns]

An alternative that might alleviate Uwe's scepticism:

Many functions such as the modelling functions have
a "call" component or attribute which is the result of

match.call()

within the function.  This makes the resulting object essentially
self-documenting.  I find it easier to write functions with the
returned object including "call" than to _accurately_ document
objects by hand.

In some settings the "call" can cause problems since it is a
language object.  This can be solved by using

deparse(match.call())

in place of the raw match.call call.
