Machine Learning in R, in a nutshell

k <- kmeans(train[,1:2],="">
plot(train[,1:2], type='n')
text(train[,1:2], as.character(k$cluster))
cm (train$class, k$cluster)

The techniques illustrated include:

While the code is concise, Josh also provides extensive comments explaining how the techniques work and are implemented in R. He’s also provided some slides to go with the script which go over the fundamentals of machine learning techniques. This is a great place to start if you’re thinking about doing some predictive analytics in R. (And don’t forget to check out the Machine Learning Task View on CRAN, too.)
