⁠Dependencies

• grpc
• protobuf
• RProtoBuf

See install for my installation notes...

⁠Examples

There are runnable examples in the demo/ folder.

⁠Hello, World!

To start a HelloWorld server:

R -e 'demo("helloserver", "grpc")'

To run a client against a running HelloWorld server:

R -e 'demo("helloclient", "grpc")'

Both are cross compatible with the Node, Python and C++ Greeter examples provided by the grpc library.

⁠Live scoring

There's a simple trained on the iris dataset and making that available for scoring via a gRPC service:

R -e 'demo("iris-server", "grpc")'

An example client to this service from R:

R -e 'demo("iris-client", "grpc")'
