Learn R Programming

⚠️There's a newer version (1.98-1.17) of this package.Take me there.

RCurl (version 0.91-0)

HTTP request interface

Description

The package allows one to compose HTTP requests to fetch URIs, post forms, etc. and process the results returned by the Web server. This provides a great deal of control over the HTTP connection and the form of the request while providing a higher-level interface than is available just using R socket connections. Additionally, the underlying implementation is robust and extensive, supporting SSL/HTTPS, cookies, redirects, authentication, etc.
