as a form of multidimensional scaling (or maybe in the oposite way).

¿Did you do your homework before posting? ¿Did you read the posting guide?
I do not know of anything in R, but searching the web gives a lot of info,
there is a good article in wikipedia, and there are a lot of papers accessible.
Code, which probably can be used with R, can be found on the
for an alternative (lasso) approach, look at the packages (CRAN)
grpreg, grplasso, glmnet, penalized and certainly some others.
