[R] RFE: bQuote like sQuote

[Jack Tanner]

I'm writing SQL queries, and it's very handy to be able to use sQuote for string
parameter values. It makes me wish that I could use an sQuote-like function for
enclosing column names and other identifiers in backticks, i.e., select `foo`
from `table`. Obviously I can do this with paste(), I'm just asking for
syntactic sugar.

Oh, a buglet: the sQuote help page, See Also section, the reference to Quotes
{base} is not hyperlinked.
