Hi, I'm using ESS 5.2.8 on GNU Emacs 21.3.1 on a Fedora Core 3 Linux 
system trying to turn off ess-smart-underscore. I find it to be annoying 
and surprising behavior considering how often underscores are used in 

The readme <http://ess.r-project.org/Manual/readme.html> says that I 
should be able to turn this off using (ess-smart-underscore nil) in my 
.emacs file. However, I get this error:

Could you please make a suggestion on how I can fix this?
