You’ll not only learn how to program in R, but also how to find the right user-contributed R packages for statistical modeling, visualization, and bioinformatics.

The author introduces you to the R environment, including the R graphical user interface and console, and takes you through the fundamentals of the object-oriented R language. Then, through a variety of practical examples from medicine, business, and sports, you’ll learn how you can use this remarkable tool to solve your own data analysis problems.

“I am excited about this book. R in a Nutshell is a great introduction to R, as well as a comprehensive reference for using R in data analytics and visualization. Adler provides ‘real world’ examples, practical advice, and scripts, making it accessible to anyone working with data, not just professional statisticians.”
