Hi Andrew,
I don't have any experience in this area but I was intrigued by your
question. Here is what I learned.

1, A bit of poking around turned up a thread on stats.stackexchange that
mentions that "smallest space analysis" (SSA) is a special case of
"multidimensional scaling" (MDS).
See the thread here:

2. The R package SMACOF implements some solutions for MDS. See the
documentation "Multidimensional Scaling in R: SMACOF" available at
