An Introduction to Statistical Programming Methods with R 책 저자
2017년 8월 - 2018년 1월 · 6개월
This book intends to present the basic tools to statistical programming and software development using the wide variety of tools made available through R, from method-specific packages to version control programs. The general goals of the book are therefore the following: • understand data structures in order to appropriately manage data, computer memory and computations; • manipulate data structures through controls, instructions, and tailored functions in order to achieve a desired output; • create new software tools (packages and web applications) that accommodate a previously unmet need; • learn how to manage software development via version control tools (e.g., GitHub) and create documentation for this software (with embedded code) to allow others to make use of the software.
