title: Using functions inside environment and only here
body: <p>I have a little question about environment in R.
  I have an environment (let's call it <code>my.env</code>) inside my <code>globalEnv</code> and I'd like to define a function that will only use the variables inside <code>my.env</code>, so I wont have to call them <code>fun(my.env$foo)</code> but just <code>fun(foo)</code>.</p>
  
  <p>Is there a way to do that ?</p>
