Modern and Flexible Web Client for R
The curl and curl_download functions provide highly configurable drop-in replacements for base url and download.file with better performance, support for encryption https//, ftps//, ‘gzip’ compression, authentication, and other ‘libcurl’ goodies. The core of the package implements a framework for performing fully customized requests where data can be processed either in memory, on disk, or streaming via the callback or connection interfaces. Some knowledge of ‘libcurl’ is recommended; for a more-user-friendly web client see the ‘httr’ package which builds on this package with HTTP specific tools and logic.
