A suite of functions to ping 'URLs' and to time
    'HTTP' 'requests'. Designed to work with 'httr'.

Tools for emitting the 'Problem Details' structure defined in
  'RFC' 7807 <https://tools.ietf.org/html/rfc7807> for reporting errors from
  'HTTP' servers in a standard way.

HTTP Request protocols. Implements the GET, POST and multipart POST request.

Testing and documenting code that communicates with remote servers
    can be painful. Dealing with authentication, server state,
    and other complications can make testing seem too costly to
    bother with. But it doesn't need to be that hard. This package enables one
    to test all of the logic on the R sides of the API in your package without
    requiring access to the remote service. Importantly, it provides three
    contexts that mock the network connection in different ways, as well as
    testing functions to assert that HTTP requests were---or were
    not---made. It also allows one to safely record real API responses to use as
    test fixtures. The ability to save responses and load them offline also
    enables one to write vignettes and other dynamic documents that can be
    distributed without access to a live server.

    use 'httr2'. It enables testing all of the logic
    on the R sides of the API without requiring access to the
    remote service, and it also allows recording real API responses to use as
    test fixtures. The ability to save responses and load them offline also

Provides low-level socket and protocol support for handling
    HTTP and WebSocket requests directly from within R. It is primarily
    intended as a building block for other packages, rather than making it
    particularly easy to create complete web applications using httpuv
    alone.  httpuv is built on top of the libuv and http-parser C
    libraries, both of which were developed by Joyent, Inc. (See LICENSE
    file for libuv and http-parser license information.)
