From org-babel docs...

The following options are mutually exclusive, and specify how the 
results should be collected from the source code block.

------------------------------------------------------
value
    This is the default. The result is the value of the last statement 
in the source code block. This header argument places Org-babel in 
functional mode. Note that in some languages, e.g., python, use of this 
result type requires that a return statement be included in the body of 
the source code block. E.g., :results value.

output
    The result is the collection of everything printed to stdout during 
the execution of the source code block. This header argument places 
Org-babel in scripting mode. E.g., :results output.
-------------------------------------------------------

So, add ":results output" to your source header block.

Or, you might want to define your R function to return a list of the 
three components you're after for further processing, and then not have 
to include ":results output"

Instead of the 3 print statements, which don't create objects, you could 
substitute

list(xbar, lower.ci, upper.ci)
