R programming, Random forest through caret

Question

I'm newbie in R and I want to implement the random forest algorithm using the caret package.

Is there any useful tutorial, step by step?

Answer 1

Most packages contain a manual, and many also include vignettes.

A quick look at the CRAN page for caret http://cran.r-project.org/web/packages/caret/index.html shows that this packages is particularly well documented.

It contains 4 vignettes:

• caret Manual – Data and Functions
• caret Manual – Variable Selection
• caret Manual – Model Building
• caret Manual – Variable Importance

Start there.
