This book will teach you how to do data science with R: You’ll learn how to get your data into R, get it into the most useful structure, transform it, visualise it and model it. In this book, you will find a practicum of skills for data science. Just as a chemist learns how to clean test tubes and stock a lab, you’ll learn how to clean data and draw plots—and many other things besides. These are the skills that allow data science to happen, and here you will find the best practices for doing each of these things with R. You’ll learn how to use the grammar of graphics, literate programming, and reproducible research to save time. You’ll also learn how to manage cognitive resources to facilitate discoveries when wrangling, visualising, and exploring data.

The most recent World Bank estimates of total population, gross domestic product (GDP), and gross national income (GNI). The tables include a ranking of countries both by total size and in per capita terms
Since 2004, the Ranking Web is published two times (January & July) per year. This ranking has the largest coverage with more than 16,000 Higher Education Institutions worldwide listed in the Directory. Web presence measures the activity and visibility of the institutions and it is a good indicator of impact and prestige of universities. Rank summarizes the global performance of the University, provides information for candidate students and scholars, and reflects the commitment to the dissemination of scientific knowledge.
Designed and produced by the World Wide Web Foundation, the Web Index is the world's first multi-dimensional measure of the Web's growth, utility and impact on people and nations. First edition in 2012 covers 61 developed and developing countries, incorporating indicators that assess the political, economic and social impact of the Web, as well as indicators of Web connectivity and infrastructure. It will be published annually. It will eventually allow for comparisons of trends over time and the benchmarking of performance across countries, continuously improving our understanding of the Web's value for humanity.
