Hi Lalitha,
Your description is more like calculating a composite score from the
values observed on ten attributes, which can then be ranked. Perhaps
you want to standardize the observed values to insure that the result
is not dominated by the attribute with the numerically highest
variance. For example:

V1<-rnorm(10,5,5)
Z1<-scale(V1)

You can then combine your ten standardized (Z) scores to form a
composite score and rank your subjects on that.

Jim

If you know what methods you want to apply, and have read the introductory R documentation, then this is an appropriate place to ask for help on how to apply R to your problem. If that is the case, then DO read the Posting Guide and try again with some example data and if possible some sample results you expect to get. We can then show you how to connect the dots using R.
