Using BigQuery with R for Analyzing Data

I plan to use Google BigQuery (please feel free to suggest non Amazon non Azure services including by Google ) to do the following- a) Analyze using R specifically for data mining, dashboards and text mining. Both R and Google platforms are a fixed given. My question is how and where do I find how to use R with Google Big Query. I read the RCurl documentation but got a bit flummoxed. Do you have a single use case for simple tasks that can be done with R and Google BigQuery.
