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

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) >

I'm having speed problems with the SCSI card we're using to do tape backup. It seems to be functioning in 16 bit mode and the current thinking is that perhaps it's using a legacy driver instead of the correct one. The Adaptec site has a 'driver' for RHEL5 which I've downloaded and tried to install but it seems to have a problem installing on a CentOS-5 system. [root at

Dear sir or ma'am, I have a question about the dataset "fgl." The dataset seems to be in the "VR" package, so I tried to download it from CRAN. However, after downloading, when I tried to load the package, it was not in my package list. I am wondering what is wrong. Any advice on how to access the fgl dataset would be appreciated. Thanks. Seungho Huh

Hello, As a new user of R (less than a month) I have got my hands on several books and am pouting through the net looking for help in gaining understanding of this powerful tool. I am becoming more proficient with using basic functions to conduct basic statistics. I am now looking to learn how to write code. After a few small worthless functions I decided to try to create a function that was

Hello, I have a question about the lars package. I am using this package to get the coefficients at a specific LASSO parameter s. data(diabetes) attach(diabetes) object <- lars(x,y,type="lasso") cvres<-cv.lars(x,y,K=10,fraction = seq(from = 0, to = 1, length = 100)) fits <- predict.lars(object, type="coefficients", s=0.1, mode="fraction") Can I assign

Thanks for the support.

This page (http://www.networkupstools.org/support.html) says that to take a driver log NUT should be stopped, so I won't be able to tell when these events occurred within a driver log. Hmm, I didn't realize it said that, but I think that's to prevent having two copies of the same driver

All, Please help me defend Samba. We are having major performance problems when using VisualStudio to build projects. The source lives on the server, and the intermediate files are dumped locally to try to speed things up. One of the engineers downloaded a demo of NetManage/Chameleon NFS and it was significantly faster. Here are some numbers: samba-1.9.18p8 samba-1.9.18p8

Hi everyone, I'm trying to solve a problem about how to get the Fisher's discriminant functions of a "lda" (linear discriminant analysis) object, I mean, the object obtained from doing "lda(formula, data)" function of the package MASS in R-project. This object gives me the canonical linear functions (n-1 coefficients matrix of n groups at least), and only with this
