Dear Mike,

This is Kisoo, How are you?

Could I make R MDS Model like PCA Model?

If I already made PCA Model from 18 Ligands, I can draw XY plot from PC1 and PC2.

and I can add additional point(data) on it plot.

In other words, PCA Model makes Equation for Principle Component, So I can calculate external ligand set using existing PC equation.

But MDS is look like different.

I cannot take any Model or Equation from "R Nonmetric MDS Component"

So, I take diffrent xy coordinate of same ligand if I using different data set.

How can I solve this issue?

Best Regard.

Kisoo.
