Hi, I have two related questions. 1. In the help page for `attach` under "Details" it says in paragraph 3: "By default the database is attached ..."
But then paragraph 4 starts: "The database is not actually attached." Could somebody explain this contradiction? Is the data(base) attached or not? 2. What is meant by the 5th paragraph: "One useful ‘trick’ is to use what = NULL (or equivalently a length-zero list) to create a new environment on the search path into which objects can be assigned by `assign` ... "? I don't understand what this "trick" is or why a "trick" needs to be performed here.
