Dears, Using the LDA function of MASS package I can project my data into one dimension. It returns the coefficients that leads to the dimension of maximum separation (e.g. model$scaling), so far so good. Question: how can I get two or four dimensions? That is, instead of project my data using only one dimension, how can I use 4 dimensions? Anyone can help me? thanks for all. ************************************************* |????????| - Anderson de Rezende Rocha Bacharel em Ci?ncia da Computa??o - UFLA Mestrando em Ci?ncia da Computa??o - UNICAMP Esteganografia e estegan?lise digital UNIVERSIDADE ESTADUAL DE CAMPINAS, SP - BRASIL < http://andersonrocha.cjb.net >
