General Network (HTTP/FTP/...) Client Interface for R R package RCurl version 1.98-1.19 CRAN Task View: WebTechnologies (https://CRAN.R-project.org/view=WebTechnologies) A wrapper for 'libcurl' <https://curl.se/libcurl/> Provides functions to allow one to compose general HTTP requests and provides convenient functions to fetch URIs, get & post forms, etc. and process the results returned by the Web server. This provides a great deal of control over the HTTP/FTP/... 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 FTP/FTPS/TFTP (uploads and downloads), SSL/HTTPS, telnet, dict, ldap, and also supports cookies, redirects, authentication, etc. Software Depends: R (>= 3.4.0), methods Imports: bitops Suggests: XML Ivan Krylov <ikrylov@disroot.org> Comprehensive R Archive Network (CRAN) CRAN Team [ctb] (de facto maintainer in 2013-2026), Duncan Temple Lang [aut] (ORCID: <https://orcid.org/0000-0003-0159-1546>), Ivan Krylov [cre] BSD_3_clause + file LICENSE (https://CRAN.R-project.org/package=RCurl/LICENSE) 2026-06-03 application/tgz https://CRAN.R-project.org/package=RCurl doi:10.32614/CRAN.package.RCurl
