Why not just send it in as is.  I use SQLite (via sqldf) and here is
the way I write my SQL statements:

    inRange <- sqldf('
        select t.*
                , r.start
                , r.end
            from total t, commRange r
            where t.comm = r.comm and
                t.loc between r.start and r.end and
                t.loc != t.new
        ')
