Thanks Greg. I did in the past looked into the details of how to create a package. I did not seem too complicated, but it would be time consuming -- an then when one thinks in creating a package (even for his own use) it always a good idea to check for wrong inputs, to have all functions well documented, etc. The functions I've developed so far are not yet in this stage.
But i liked the idea of using attach(). I had overlooked this point in the attach() description. Thanks.
