ggplot2_The Elements for Elegant Data Visulization in R.pdf ggplot2 - Elegant Graphics for Data Analysis.pdf R数据可视化手册 全部高清版PDF，打包下载

ggplot2最新版，作者HadleyWickham，基于数据分析的优美绘图，gplot2包是基于Wilkinson在《Grammar of Graphics》一书中所提出的图形语法的具体实现, 这套图形语法把绘图过程归纳为data, transformation, scale, coordinates, elements, guides, display等一系列独立的步骤, 通过将这些步骤搭配组合, 来实现个性化的统计绘图。

This new edition to the classic book by ggplot2 creator Hadley Wickham highlights compatibility with knitr and RStudio. ggplot2 is a data visualization package for R that helps users create data graphics, including those that are multi-layered, with ease. With ggplot2, it's easy to: produce handsome, publication-quality plots with automatic legends created from the plot specification superimpose multiple layers (points, lines, maps, tiles, box plots) from different data sources with automatically adjusted common scales add customizable smoothers that use powerful modeling capabilities of R, such as loess, linear models, generalized additive models, and robust regression save any ggplot2 plot (or part thereof) for later modification or reuse create custom themes that capture in-house or journal style requirements and that can easily be applied to multiple plots approach a graph from a visual perspective, thinking about how each component of the data is represented on the final plot This book will be useful to everyone who has struggled with displaying data in an informative and attractive way. Some basic knowledge of R is necessary (e.g., importing data into R). ggplot2 is a mini-language specifically tailored for producing graphics, and you'll learn everything you need in the book. After reading this book you'll be able to produce graphics customized precisely for your problems, and you'll find it easy to get graphics out of your head and on to the screen or page.
