Hello, Does the "lda" function (package MASS) perform or can it perform classic two-group Fisher discriminant analysis? R-version: 1.9.1, MASS package (latest available) Thank you, Borut Rajer

...hi <- hi[(bw+1):nf] - hi[1:(nf-bw)] cv <- cumsum(v) cv <- cv[(bw+1):nf] - cv[1:(nf-bw)] ternaryplot(cbind(lo=lo/cv, md=md/cv, hi=hi/cv), lty=1) } produces different-looking ternary diagrams for different pieces, which is good, because my student and I are looking for ways to disriminate pieces. Of course, these diagrams, by design, leave out the time element entirely. (I do hope that nobody has patented the idea of using ternary diagrams to display the distribution of high, medium, and low notes in music.) One thing we've done is to smooth fairly heavily and then (in ef...

I am trying to follow the mclust examples in "MCLUST: Software for Model Based Clustering, Density Estimation and Disriminant Analysis" by Chris Fraley and Adrian Raftery, but I cannot reproduce the density and uncertainty surfaces for the Lansing Woods maples. I am using R 1.8.1 with the code below. The same code works fine in S-Plus 6.2 Am I missing something or is this a bug? Thanks Mike White library(mclu...
