> I wanted a data frame component to be named "next", for example:
> 
> > m <- data.frame (matrix (0, nrow=2, ncol=2))
> > names (m) <- c("prev", "next")
> > m
>   prev next
> 1    0    0
> 2    0    0
> 
> But "next" being reserved prevents $ indexing without quotes:
> 
> > m$next
> Error: syntax error
> > m$"next"
> [1] 0 0

> Although they are mostly obvious, I can't find in the documentation
> (using Jon Baron's searcher, at least) a list of these words.  Am I
> missing the documentation, or could such a list be added to a future
> release?
