This page contains links to useful websites that I often use/visit and are related to data analysis.
R-bloggers - blog aggregator that publishes high-quality articles contributed by hundreds of R bloggers.
Advanced R - I got this book before I could really understand it, but now I love it. The link will take you to the companion website, where you can read it online, or you can get a physical copy from Amazon.
Machine Learning with R - This book was my first contact with machine learning. It provides a great overview of machine learning algorithms and serves as a great reference point for more advanced topics in R and machine learning.
R-users - For R users, this site provides full-time, part-time, and freelance opportunities available worldwide. If you’re looking for R users, post a job there to get exposure in the R community.
