Opencpu and R statistics

I want to use OpenCpu to build statistical web applications. BUT, the documentation I see on the internet seems to be conflicting. Just trying to get started for newbies. Hope someone knows how. I've seen some posts here on stackoverflow and I still see contradictions. Note that I have used Rserve in java and Rpy2 in python, and these are wrappers for R-stats.

BUT on the website I see they say that OpenCpu is a built-in engine using HTTP. I want to install this OpenCpu on my local Ubuntu machine.

So my question is: (1) Does the OpenCpu server have a built-in version of R-statistics? SO downloads everything I need. OR (2) need to set R-stats separately and OpenCpu server separately, so therefore these are two separate applications that talk to each other over HTTP.

So, you can see that I have not been able to find such fundamental background knowledge on the internet.

Execution apt-get install opencpu

will automatically install R. Not because it is contained, but because it is declared as a dependency, so the package manager understands that it needs R, apache, etc. when it installs opencpu

.
