Webo Added a "downsample" function based on Peng Qiu's idea in the SPADE package. The point is to take a subsample that deliberately does *not* preserve the popultion distribution. Instead, it samples fewer items fromt he most dense areas ofg the distribution in order to preserve samples of as many clusters as possible.
