Yesterday I re-ran Plink with a narrower European-biased data set, and generated some MDS plots. I only had a few Asian and African populations, mostly so that I could replicate the standard dimensions 1 and 2, producing the classic "v-shape" which you've seen before. But what's more interesting are lower coordinates. They may not capture as much of the variation in the distance matrix, but illustrate important dynamics. I haven't used the directlabels package yet, so right now the labels are still imperfect. I'm giving black text as well as colored text. Also, here's the original data (as in MDS results, not the raw data).
