I always thought it meant "Long" (I'm assuming R's integers are long
integers in C sense (iirrc one can declare 'long x', and it being common to
refer to integers as "longs"  in the same way we use "doubles" to mean
double precision floating point).  But pure speculation on my part, so I'm
curious!
