Yes (although that questions leaves a lot of room for interpretation).

It was fairly straight-forward to build R (like any other cross- 
compilation). The tricky part is to install packages (if you are truly  
cross-compiling on another architecture) which I solved by using multi- 
arch R (which contains both arm and the host architecture) and cross- 
compiling only the binaries (i.e. only packages with native code).  
That could probably be simplified, but I didn't have the time to do  
that.
