Become an efficient data scientist with R
R is a high-level functional language and one of the must-know tools for data science and statistics. Powerful but complex, R can be challenging for beginners and those unfamiliar with its unique behaviors. Learning R Programming is the solution – an easy and practical way to learn R and develop a broad and consistent understanding of the language. Through hands-on examples you’ll discover powerful R tools, and R best practices that will give you a deeper understanding of working with data. You’ll get to grips with R’s data structures and data processing techniques, as well as the most popular R packages to boost your productivity from the offset.
Start with the basics of R, then dive deep into the programming techniques and paradigms to make your R code excel. Advance quickly to a deeper understanding of R’s behavior as you learn common tasks including data analysis, databases, web scraping, high performance computing, and writing documents. By the end of the book, you’ll be a confident R programmer adept at solving problems with the right techniques.
