Data Analysis and Prediction Algorithms with R

This book introduces concepts and skills that can help you tackle real-world data analysis challenges. It covers concepts from probability, statistical inference, linear regression, and machine learning. It also helps you develop skills such as R programming, data wrangling with dplyr, data visualization with ggplot2, algorithm building with caret, file organization with UNIX/Linux shell, version control with Git and GitHub, and reproducible document preparation with knitr and R markdown. The book is divided into six parts: R, Data Visualization, Data Wrangling, Statistics with R, Machine Learning, and Productivity Tools. Each part has several chapters meant to be presented as one lecture and includes dozens of exercises distributed across chapters.
