I am not sure I understand your question, but you may want to have a
look at ?scale.  It might get you started.

One way is the rescaler method in the reshape package.  It can scale
to common range, mean 0 sd 1, or ranks.  Compared to scale, which
others have mentioned, it will work on data.frames, leaving
categorical variables unchanged.
