[S] cmdscale with similarities?

Dear S+Users,

I would like to obtain a graphical representation of the distances
and proximities between points.

The cmdscale function can be used for a distance structure.
Nevertheless the data I use represent similarities,
that is to say the higher the values, the nearer the points.

Does a solution to this problem exist?

Is there a way to change the similarities into distances?

Thank you very much for your help
