See the help for .Last:
Immediately _before_ terminating, the function '.Last()' is
executed if it exists and 'runLast' is true. If in interactive use
there are errors in the '.Last' function, control will be returned
to the command prompt, so do test the function thoroughly.
You can avoid it via arguments to q() (see its help). However, if the
'fame' package has been ill-mannered enough to put a .Last in your
workspace, then you can and should delete it and re-save the workspace.
I can't see the function "validServerIsRunning" in the current fame
package, so it may be a legacy of a workspace from an earlier version.
Packages really should not be using the user's workspace, and in
particular not setting .Last there. A couple of packages do have .Last in
their space, but it is not guaranteed that their version will be visible:
reg.finalizer() is the way to do this in a package.

Hello list member:
I've recently had a problem in that I'm unable to quit an R Session. I
noticed this after the update to 2.8.0, but I believe I also noticed it on
another machine, in the previous version. It occurs on both linux and Mac
platforms. It only occurs when I start R in some particular workspaces that
have alot of objects in them; it does not occur if I start R in an empty
workspace. I dont have to do anything in the workspace after starting R to
get this to occur, and no packages are loaded by default. Here's a summary
from a Linux environment:

}
<environment: namespace:fame>
------------------------------------------
As the .Last function is referring to the fame package, I figure it must be
something to do with that. There are objects in the workspace that require
fame to be loaded, but at this point, I have not loaded the fame package, or
accessed those objects. If loaded, the same error occurs when trying to quit.
Thanks in advance for any suggestions on how to troubleshoot this.
Dan
