Hello, world!

This is a basic JSON RPC call to OpenCPU. We use ocpu.rpc from the opencpu.js library to call the R function called hello included in this R package.

Have a look at the HTML source code! Some things to notice:

• We can always see the source code of the R function using the API, e.g here.
• If the R function has a manual page, it we can find it here
• When the name field is empty, the R function raises an error. Notice how we deal with this in javascript.
