商品描述
Want to use the power of R sooner rather than later? Don't 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 R's 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, Facebook's 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.
商品描述(中文翻譯)
想要更早地利用 R 的強大功能嗎？沒有時間去翻閱冗長的文本和線上手冊？使用這本書來快速、簡單地編寫代碼，讓您的專案迅速啟動。它包含適用於多個學科的代碼和範例。這本書以日常語言撰寫，盡量減少複雜性，每一章提供您所需的基礎構件，以便將 R 的驚人能力應用於您的分析、報告和視覺化需求。
CRAN Recipes 認識到不必要的行話和複雜性會妨礙您的進展。忙碌的專業人士需要簡單的範例和直觀的描述；旁支末節和迂迴的哲學討論留給其他書籍。
在這裡，R 腳本被壓縮到盡可能的複製-粘貼-運行格式。章節和範例的結構是基於目的而非特定功能（例如，「髒數據清理」而不是 R 套件名稱「janitor」）。日常語言消除了事先了解函數/套件的必要性。
您將學到什麼
- 執行輸入/輸出；視覺化；數據處理；群組層級的操作；以及快速數據探索
- 處理預測（多變量、時間序列、邏輯回歸、Facebook 的 Prophet 等）
- 使用文本分析；抽樣；財務分析；以及高級模式匹配（正則表達式）
- 使用 DPLYR 操作數據：過濾、排序、總結、向數據集添加新字段，並應用強大的 IF 函數
- 使用聯接創建文件的組合或子集
- 使用管道編寫高效代碼，以消除中間步驟（MAGRITTR）
- 處理各類字符串/字符操作（STRINGR）
- 發現計數、模式以及如何定位整個單詞
- 進行通配符匹配、提取和反向匹配
- 使用 LUBRIDATE 處理日期
- 修正髒數據；吸引人的格式；需要避免的壞習慣
