Von der hinteren Coverseite

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, tibble, forcates, lubridate, stringr, tidyr, magnittr, dplyr, purrr, ggplot2, modelr, broom, knitr, shiny, 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.  

You will:

• Get started with RMarkdown and notebooks
  
• Import data with readr
  
• Work with categories using forcats, time and dates with lubridate, and strings with stringr
  
• Format data using tidyr and then transform that data using magrittr and dplyr
  
• Write functions with R for data science, data mining, and analytics-based applications
  
• Visualize data with ggplot 2 and data fit for models using modelr and broom
  
• Report results with markdown, knitr, shiny, and more
