in plain english

This repository contains the code examples that accompany the 2012 O'Reilly book "Machine Learning for Hackers," written by Drew Conway and John Myles White. The book was aimed at programmers who wanted to learn machine learning through practical examples rather than theory-first explanations. All the code is written in R, a programming language commonly used for statistics and data analysis. To run the examples, you need R installed along with several supporting libraries. Some of those libraries (RCurl and XML) also require external software on your machine. The repository includes a setup script called package_installer.R that handles installing the required R libraries in one step. The README notes that the code may not match the book exactly, since comments and small changes have been added since publication. The source code is released under the Simplified BSD License, and any images or outputs produced by the code fall under Creative Commons Attribution-Share Alike 3.0. This is a companion resource, not a standalone application, so its main use is reading alongside the book.
