## 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.
