I use knncat to make a predictive model and get misclass rate > knncat.m<-knncat(training.new,k=c(10,20),classcol=5) > knncat.m Training set misclass rate: 36.88% then I try to calculate prediction accuracy by the following: > pr.knncat.train <- predict (knncat.m,training.new,training.new,t...

Hi, Until recently I was using the knncat classifier function of knncat on an old computer (2.12, Mac OS X 10.4), and everything worked great. However, now that I have updated to R 2.14.1 (on Mac OS X 10.7), knncat seems broken. Problems: 1. It seems to output verbose output by default, and regardless of whether I put 0 or 1 into t...

Hi all, I am wondering if anyone has problem installing 'knncat' package. I tried to install using 'Rcmd INSTALL knncat_1.1.1.tar.gz', error message appeared. I attached the message in the end. I allso tried to install from RGui, but it was not listed. Thanks in advance. Regards, jenny ---------- Making package knncat ------------ adding...

Hi there fellow R-users, Does anyone know if there is a package for k nearest neighbours prediction as opposed to classification? I have found the package knncat but can't see a way to adjust it to predict a continuous variable. Any help would be great, Regards Wayne Jones KSS Ltd Seventh Floor St James's Buildings 79 Oxford Street Manchester M1 6SS England Company Registration Number 2800886 Tel: +44 (0) 161 228 0040 Fax: +44 (0) 161 2...

I want to speed up computations (involving matrices) by writing some C-code to be loaded. In the C-code, I need to invert matrices etc. As I've understood the "writing R extensions" doc, I can use use #include <R_ext/Linpack.h> in my .c-file and get access to linpack's facilities within my C-code. Is that correct? If so, can anyone point me to examples on how this is

What happened to the category k-means package for performing k-means clustering on categorical variables? I expected it to become more prominent after the Netflix Challenge recommendation engine contest concluded, but instead it seems to have dropped from view. Where was it and where is it now, and why did it become less visible?
