Want to use the power of R sooner rather than later? Dont have time to plow through wordy texts and online manuals? Use this book for quick, simple code to get your projects up and running. It includes code and examples applicable to many disciplines. Written in everyday language with a minimum of complexity, each chapter provides the building blocks you need to fit Rs astounding capabilities to your analytics, reporting, and visualization needs. CRAN Recipes recognizes how needless jargon and complexity get in your way. Busy professionals need simple examples and intuitive descriptions  side trips and meandering philosophical discussions are left for other books. Here R scripts are condensed, to the extent possible, to copy-paste-run format. Chapters and examples are structured to purpose rather than particular functions (e.g., dirty data cleanup rather than the R package name janitor). Everyday language eliminates the need to know functions/packages in advance. What You Will Learn Carry out input/output  visualizations  data munging  manipulations at the group level  and quick data exploration Handle forecasting (multivariate, time series, logistic regression, Facebooks Prophet, and others) Use text analytics  sampling  financial analysis  and advanced pattern matching (regex) Manipulate data using DPLYR: filter, sort, summarize, add new fields to datasets, and apply powerful IF functions Create combinations or subsets of files using joins Write efficient code using pipes to eliminate intermediate steps (MAGRITTR) Work with string/character manipulation of all types (STRINGR) Discover counts, patterns, and how to locate whole words Do wild-card matching, extraction, and invert-match Work with dates using LUBRIDATE Fix dirty data  attractive formatting  bad habits to avoid Who This Book Is For Programmers/data scientists with at least some prior exposure to R.
