Re: [R] Stress with MDS

I presume this is isoMDS which is part of package MASS, support software for a book. The definitions of 'stress' are in that book, and the source code is part of the package. It makes no sense to use a metric definition of stress with a non-metric method of fitting: the original and fitted dis

[R] Stress with MDS
