Multidimensional scalling
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! Best tomek

It depends on what you mean? If you would like a goodness of fit of your ordination to your distance matrix then this is doable and I would suggest that you look at the labdsv tutorial - http://ecology.msu.montana.edu/labdsv/R/ On Thu, Jan 29, 2009 at 6:50 PM, Tomek Wlodarski <tomek.wlodarski at gmail.com> wrote:
Dear R developers and users! I have calculated metric MDS by cmdscale from matrix of distances (dissimilarities). I would like to ask you how can I estimate how well this new mapping represents characteristic features of my data set? Thank you for any suggestions. Best, tomek
