The following example demonstrates the combination of header arguments
required to generate the correctly named output.
#+name: input
| 1 | 2 |
| 2 | 4 |
| 3 | 9 |
#+NAME: pvals_waw
#+headers: :var input=input
#+BEGIN_SRC R :results graphics :file output.pdf
plot(input)
#+END_SRC
after evaluating the code block I get
#+RESULTS: pvals_waw
[[file:output.pdf]]
This should be documented on Worg, but there is no doubt that there is
still work to be done on language-specific header argument
documentation.
