## Introduction

**RWsearch** stands for « Search in R packages, task views, CRAN and in the Web ». 

This vignette introduces the following features cited in the README file:

.13. Use some **bookmarks to various websites and search engines**. Keywords can be typed directly in the R console and are sent to the search engine, then displayed in your browser. The list of the search engines is expected to grow (with your help).



## Explore the web

Web search engines are major tools to explore the web. Some search engines explores the full web when some other search engines are restricted to a specific website. To remember their favorite search engines, people record them as bookmarks (favorites) in their browser. Why not store them directly in a R package and hide in the R functions the specific syntax of each search engine? This is the **W** of **RWsearch**.

This version of **RWsearch** has aleady referred more then 60 web search engines. We expect this number to grow thanks to the contribution of everyone.
