Hi, has anyone ever seen implemented in R the following "geodesic" distance between positive definite pxp matrices A and B? d(A,B) = \sum_{i=1}^p (\log \lambda_i)^2 were \lambda is the solution of det(A -\lambda B) = 0 thanks stefano

Dear R users. I have data observed on the surface of a torus, and am trying to fit the nonlinear regression using the geodesic equation on a torus. Could anyone give me a helpful advise on this problem? I would definitely appreicate your reply. Sincerely, SUNGSU KIM [[alternative HTML version deleted]]

Hi all, I would like to know a way of calculating the distance between 2 points when I already have the longitude and latitude of the points. For example : Point 1 : 52? 9'54.00"N 4?25'8.40"E Point 2 : 52?27'46.80"N 4?33'18.00"E Distance between point 1 and point in km .... Is there any functions already available for this ? Any help will be much

...he probabilities with which the objects are discriminated from each other by a perceiving system. In addition to the oriented and overall Fechnerian distances, the package fechner also computes such related information as the points of subjective equality, the psychometric increments, the geodesic chains and loops with their corresponding lengths, and the generalized Shepardian dissimilarities. Moreover, the package fechner provides functions for checking the required data format and the fundamental regular minimality/maximality condition. Best regards, Thomas Kiefer Ali Uenlue -- Dep...

...bility" (your current dist()) *and* the geographical distance, maybe giving much more weight to the geographical distance, something like D_{i,j} := d_{i,j} + w* d~(X_i, X_i) where d_{i,j} are your dist() or daisy() dissimilarities, 'w' is weight factor and d~(u,v) is e.g. the geodesic distance between u and v. I'm CC'ing this to the R-help mailing list, as I think you could get more advice from there. Martin Maechler, ETH Zurich DS> However if I do that the procedure hclust () does not work anymore.

Hi all. I am currently designing a server room. I would like to be able to draw a 2D (in the future 3D) project. Do you know any tools? Which one can you recommend? Best regards, Rafal Radecki.
