Kernel Fisher Discriminant in R?
Dear members, I am wondering if there are any functions to perform the Kernel Fisher Discriminant method, especially for multi-class problems, in R. I would appreciate any kind of information on this. Thanks for your time. Seungho Huh, Ph.D. Research Statistician RTI International North Carolina, USA [[alternative HTML version deleted]]

An array of an array of boxplots in lattice
Using the data set fgl in MASS the following code layout(matrix(1:9,3,3)) for(i in 1:9){ boxplot(fgl[,i] ~ type, data = fgl,main=dimnames(fgl)[[2]][i])} produces a 3 by 3 array of plots, each one of which consists of six boxplots. Is it possible to do this in lattice? Steve "R version 2.7.2 (2008-08-25)" on Ubuntu 6.06

Reading data for discriminant analysis
Dear R users, I want to do discriminant analysis on my data. I have successfully followed the discriminant analysis in V & R on the iris data: > ir <- rbind (iris3[,,1],iris3[,,2],iris3[,,3]) > ir.species <- c(rep("s",50),rep("c",50),rep("v",50)) > a <- lda(log(ir),ir.species) > a$svd^2/sum(a$svd^2) [1] 0.996498601 0.003501399 > a.x <-

how to obtain predicted labels for test data using "kerne lpls"
You need to do some extra work if you want to do classification with a regression method. One simple way to do classification with PLS is to code the classes as 0s and 1s (assuming there are only two classes) or -1s and 1s, fit the model, then threshold the prediction; e.g., those with predicted values < 0.5 (in the 0/1 coding) get labeled as 0s. There's a predict() method for mvr

how to obtain predicted labels for test data using "kernelpls"
Dear members, My name is Seungho Huh. I am a statistician who tries to use the Kernel PLS method in a classification problem. I am sending this email to ask you something about the "kernelpls" function in R (pls.pcr package). I would like to obtain the predicted Y values for test data, using the Kernel PLS method. Let's take the example in the R help: > data(NIR) >

LLVM Backend for a platform with no (normal) stack
Dear Sir or Ma'am; I have found a wealth of help and information on writing an LLVM backend. And, my platform has no stack. Can you point me to any information that would specifically address creating a backend for this kind of platform? In previous wanderings, I thought I ran across a phrase "platforms with no stack such as FPGAs", but I can't find that mention, now.

Some people asked me lately about how professional Dovecot is.
I purely love that kind of crap. As if presentations meant anything, as if there aren't all kinds of scholarly work about theoretical perfect world algorithms and conceptual systems that will never be implemented and are as practical and effective as wings on a pig. Please. I'm reminded of the story about how, during the American Civil War, when the North had finally, after years of

multi-class classification using rpart
Hi, I am trying to make a multi-class classification tree by using rpart. I used MASS package'd data: fgl to test and it works well. However, when I used my small-sampled data as below, the program seems to take forever. I am not sure if it is due to slowness or there is something wrong with my codes or data manipulation. Please be advised ! The data is described as the output from str()
