Data Manipulation with R pdf epub mobi 圖書描述

This book presents a wide array of methods applicable for reading data into R, and efficiently manipulating that data. In addition to the built-in functions, a number of readily available packages from CRAN (the Comprehensive R Archive Network) are also covered. All of the methods presented take advantage of the core features of R: vectorization, efficient use of subscripting, and the proper use of the varied functions in R that are provided for common data management tasks. Most experienced R users discover that, especially when working with large data sets, it may be helpful to use other programs, notably databases, in conjunction with R. Accordingly, the use of databases in R is covered in detail, along with methods for extracting data from spreadsheets and datasets created by other programs. Character manipulation, while sometimes overlooked within R, is also covered in detail, allowing problems that are traditionally solved by scripting languages to be carried out entirely within R. For users with experience in other languages, guidelines for the effective use of programming constructs like loops are provided. Since many statistical modeling and graphics functions need their data presented in a data frame, techniques for converting the output of commonly used functions to data frames are provided throughout the book.

還行的簡介。不過確實記不住。

評分

中文已齣西安交大,翻譯略次

評分

案頭常備書,R的書要麼看精的要麼看專的,此書屬於後者。但是遠遠沒有涵蓋R的data manipulation所有大招小計,名字改為an intro to R data manipulation更準確。前三章也基本是可以不看的,最後三章不錯。

評分

適閤對R有一定瞭解的人長姿勢。
