Improvement: function cut

Regarding your first point, argument 'include.lowest' already handles 
this specific case, see ?.bincode

Your second point, maybe it could be helpful, but since both 
'cut.default' and '.bincode' return NA if a value isn't within a bin, 
you could make something like this on your own.
Might be worth pitching to R-bugs on the wishlist.

    Hello List members,


    the following improvements would be useful for function cut (and
    .bincode):


    1.) Argument: Include extremes
    extremes = TRUE
    if(right == FALSE) {
    ??? # include also right for last interval;
    } else {
    ??? # include also left for first interval;
    }


    2.) Argument: warn = TRUE

    Warn if any values are not included in the intervals.


    Motivation:
    - reduce risk of errors when using function cut();


    Sincerely,


    Leonard
