Running R in an iOS app

I am trying to find out if this is possible

I know there is a way to run Python or Lua scripts on iOS. Also, I know there are already projects out there that make it easier to work with libraries and link components.

Question: Was this also done for the R language? I looked on the internet but only saw posts from people who did it in a jailbroken environment. Also, according to my understanding, this is not in conflict with the iOS license agreement as section 3.3.2 has been modified to allow any code that comes with the binary application to run.

Any suggestions? How to try
