Hi R lovers

Obviously I cannot use the underscore "_ " character to name an object in R
Is there a special reason for that ?

I want to use it to rename a function
maybe the problem is due to the nature of the object I work on

thanks for any comments on that very little and not very bothering trouble

Actually, you can but it is more trouble than it is worth as you will 
always have to quote the name, and often explicitly get it:

            

      
      
      
    

        
[1] 3.141593

            

      
      
      
    

        
Yes, it is allowed for assignment, but not for much longer.  Once
it is removed for assignment (1.8.0) it will be allowed as part of a name
after a decent interval.
