Subject: Function does not see variables outside the function
In-Reply-To: <CAApZs+HuWo2zuKjjEfpjsYY7E21nUEpHVgpqRimyZOReO=AVAg@mail.gmail.com>
Why would you want to impose this restriction? Perhaps if you explain what
you are trying to do, we can suggest approaches that will satisfy your
specific needs.
(note- one can always redefine whatever variables are to be "excluded." E.g.
to keep the body of a function from referring to 'foo' in the calling
environment, just add the line 'foo<-NA' inside the function)
