[R] Using "_" in names?

[Spencer Graves]

     I work with data bases that routinely use the underscore, "_", as 
part of names.  I've seen discussion on this list of possibly allowing 
that in a future release of R.  How far are we away from that? 

     I got the following from R 1.8.0 under Windows 2000: 

> A_1
Error: syntax error
> A_B <- 1
Error: syntax error
> "A_B" <- 1
> DF <- data.frame(A_B=1)
Error: syntax error
> DF <- data.frame("A_B"=1)
> DF
 A.B
1   1
> names(DF) <- "A_B"
> DF
 A_B
1   1
> lm("A_B"~1, DF)
Error in terms.formula(formula, data = data) :
       invalid term in model formula
     Thanks for your help,
     Spencer Graves
