[R] about the char _

[Fan]

Dear all,

I don't know the historical reason why the char '_' was 
defined in the R language grammar as a synonyme of the 
assignment <-, anyway the R documentation dosen't recommand 
its usage.

Well, this is a real "incompatibility issue" each time
we need to interface R with other language/systems, notably with 
database systems. Recall that, in perhaps all computer systems, 
the char '_' can be used in the name of a variable or a column 
in a data table.

So that's my question : is there an option to change this
behaviour ? 

All that I want is the possibility to use the same name of 
variables in my R source as they are declared in the other systems.

Thanks
