Hi Graham,

Here's a version of your example that works.

Dan


* test
#+srcname:trial
#+begin_src R
c(4,5,6,7,8,9)
#+end_src

Note I deleted the 'x <-' there. Unless you're using :session there's
no point assigning to a variable which is not used.

#+results: trial
| 4 |
| 5 |
| 6 |
| 7 |
| 8 |
| 9 |

* meantest
#+srcname: calcmean(data=trial)
#+begin_src R
mean(data)
#+end_src

#+results: calcmean
: 6.5

or alternative syntax

#+begin_src R :var data=trial
mean(data)
#+end_src

#+results:
: 6.5
