    Many thanks for this. Just in case others hit the same issues:
    When I pasted in your code from slides, it did not work because the quotes pasted as curly quotes. All fine when turned into straight quotes.

    I am using R2.15.3.
    rjson is not compatible with this, but RJSONIO works fine
