All, 1. Is there a command that tells you what libraries are loaded? 2. How do you remove a library that has been loaded? 3. If you have loaded a library that masks previously loaded objects, how can you tell which object is being run? In Matlab, I would run "which f" to determine the location of the file f that will be run. Is there a similar procedure in R?
