Graphical Data Analysis with R (Hardcover)

See How Graphics Reveal Information

Graphical Data Analysis with R shows you what information you can gain from graphical displays. The book focuses on why you draw graphics to display data and which graphics to draw (and uses R to do so). All the datasets are available in R or one of its packages and the R code is available at rosuda.org/GDA.

Graphical data analysis is useful for data cleaning, exploring data structure, detecting outliers and unusual groups, identifying trends and clusters, spotting local patterns, evaluating modelling output, and presenting results. This book guides you in choosing graphics and understanding what information you can glean from them. It can be used as a primary text in a graphical data analysis course or as a supplement in a statistics course. Colour graphics are used throughout.

《使用圖形揭示資訊》

《使用 R 進行圖形資料分析》向您展示了從圖形顯示中可以獲得的資訊。本書著重於為何要繪製圖形來顯示資料以及應該繪製哪些圖形（並使用 R 進行繪製）。所有資料集都可在 R 或其套件中找到，相關 R 程式碼可在 rosuda.org/GDA 上取得。

圖形資料分析對於資料清理、探索資料結構、檢測異常值和不尋常群體、識別趨勢和群集、發現局部模式、評估建模輸出以及呈現結果都非常有用。本書指導您選擇圖形並理解從中可以獲得的資訊。它可以作為圖形資料分析課程的主要教材，或作為統計課程的補充教材。全書使用彩色圖形。
