Re: clusterdump samplePoints parameter

Can you please clarify as to whether the points are somehow ordered if 
the number of points are specified? In other words, suppose I set max 
points = 100 and there are 1000 points in a cluster. Which 100 of the 
1000 points are returned? Alphanumeric sort of point ID, etc?
