R Analysis

This wiki is designed to help anyone perform statistical analyses on their data using R. It is divided into 3 broad sections: the first section outlines basics of how R deals with data using built in data sets, the second will help you to read in and organize your own data, and the third will help to summarize and run stats on your data and output graphs.

Each section is organized into a series of questions; start from the beginning if you are new to R, otherwise click on a question to go to a detailed answer and/or examples.

To get started, download R for free from the R website
