Dear Stephen, Thanks a lot! now I see that cmdscale is not the best option for my problem So I am wondering if you can advice me other method of MDS or different approach to my problem: I have matrix which describes "distances" between object and I would like to visualise this matrix onto 2D in such way that distance between each object on this map would be somehow proportional to "distances" between respective points in the matrix. Thanks!
