Thanks for the answers Uwe! So this is a common problem in biology - few number of cases and many, many variables (genes, proteins, metabolites, etc etc)! Under these conditions, is discriminant function analysis not an ideal method to use then? Are there alternatives? 1) First problem, I

Dear All This is more of a statistics question than a question about help for R, so forgive me. I am using lda from the MASS package to perform linear discriminant function analysis. I have 14 cases belonging to two groups and have measured each of 37 variables. I want to find those variables

Dear R Users, I'm very very interested in learning how to use R to carry out a classification of data using discriminant function analysis. I've found the MASS package and the lda function, but the examples in the help system are a bit over my head. I'm not exactly sure how to interpret the
