A graphics device for R that is accessible via network protocols.
This package was created to make it easier to embed live R graphics in
integrated development environments and other applications.
The included 'HTML/JavaScript' client (plot viewer) aims to provide a better overall user experience when dealing with R graphics.
The device asynchronously serves graphics via 'HTTP' and 'WebSockets'.

Report Errors in Web Applications with 'Problem Details' (RFC

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.

Testing code and packages that communicate with remote servers can
be painful. Dealing with authentication, bootstrapping server state,
cleaning up objects that may get created during the test run, network
flakiness, 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 test
contexts that mock the network connection in different ways, and it offers
additional expectations to assert that HTTP requests were--or were
not--made. Using these tools, one can test that code is making the intended
requests and that it handles the expected responses correctly, all without
depending on a connection to a remote API.
