plot() has to make a decision about the extent of the axis and the 
position of axis markers. It tries to make them nice and round: it makes 
more sense to place markers at 0, 200, 400, 800, 1000   than 1  210.5   
420   629.5, but as a consequence, you get the extra space between 839 
and 1000.

If you want to override that, you have to declare your own axis e.g. 
by    axis([1,839])
