[R] information about a function

[Rolf Turner]

It's not clear to me what you want;  the on-line help states that
approxfun() does linear or constant interpolation (the default is
linear).  It is trivial to write down a ``mathematical
representation'' of the resulting function --- but why would you want
to?  The function f() you created does the calculations for you; all
you would be doing is reinventing the wheel.
