Hello,

We are trying to find a function to compute "stress" in our
multidimensional scaling analysis of a dissimilarity matrix. We've used
"dist()" to create the matrix and "cmdscale()" for the scaling. In order
to determine the number of dimensions we would like to plot stress vs.
dimensions. However, we cannot find a pre-made command. It seems that
other programs may test stress as part of the algorithm as opposed to
cmdscale() which allows us to chose the number of dimensions. Do we need
to just code in a computation of stress? 
 
Thanks,
Michelle
