It may be that individual differences scaling is not available in R.
The classic piece of software for this purpose is SINDSCAL. It is
beautiful Fortran (although this sounds like contradiction in terms),
and it would be easy to port the software into R, but I think the
license does not allow this. The hardest bit would be to change the
output into R. I suggest you dig up SINDSCAL somewhere -- it could be
in netlib -- and compile it yourself. Gnu g77 is quite OK.
