> The R C++ bindings feature a number of cases where a data buffer is being 
> accessed when it may possibly be null in the case of a 0-length array. This 
> will cause a segfault
> https://github.com/apache/arrow/blob/master/r/src/array.cpp#L245
> I suggest defining some helper functions as we have done elsewhere to assist 
> with getting a typed offset into a buffer but passing through nullptr if the 
> buffer object is null
