In this handy,practical book you will cover each concept concisely,with many illustrative examples. You’ll be introduced to several R data science packages,with examples of how to use each of them.
In this book,you’ll learn about the following APIs and packages that deal specifically with data science applications: readr,dibble,forecasts,lubridate,stringr,tidyr,magnittr,dplyr,purrr,ggplot2,modelr,and more.
After using this handy quick reference guide,you’ll have the code,APIs,and insights to write data science-based applications in the R programming language. You’ll also be able to carry out data analysis.
