Dear Forum, I have a class variable 1 (populations A-E), and two other class variables, variable 2 and variable 3. What I want is to see if the combination of var 2 and var 3, will give me a pattern that allows to distinguish populations. I found several packages like ade4, with pcaiv function and factoMineR. but there are not working. Using the ade4 package, when I try to build the pca: pca1 <- dudi.pca(D, scan = FALSE, nf = 2) Error in v * row.w : non-numeric argument to binary operator
Does someone has suggestions?
