After a cursory online search using simply " A new method for non-parametric multivariate analysis" + CRAN + R, I got the following three packages which include this paper in their references: vegan, mefa, and TraMineR. I don't know whether they deal with the procedure you are after, but it would be worth having a look.

Subject: [R] Distance-based non-parametric ANOVA
I am comparing treatments by comparing within group to between group distances like described in
MJ Anderson. 2001. A new method for non-parametric multivariate analysis of variance.
Austral Ecology 26: 32 -- 46.
The idea is to find the ratio of within group sum of distance^2 to between group sum of distance^2. Then find the distribution of the statistic by permuting the sample.
Has anyone done this before in R code? Are there any packages (I did checked on CRAN - none). Code?
I want to make sure I won't be inventing a bicycle before I write my own package.
Comments? Suggestions? (I have never written an R package before)
Thank you for your time,
