Thank you all for the quick responses. However, I'm not sure I unterstand the scaling matrix (denote S henceforth) correcty. An observation x will be transformed by Sx into a new vector space with the properties given by the description. What is now the direction perpendicular to the seperating plane as estimated in the process of the lda? That direction is what im primarily interested in. When plotting a lda object I see diagrams with observations when the plane (here the line) of separation is chosen canonically to be {ax | a \in R}.
