Also, it appears that babel no longer supports passing variables through the #+name: line. I don't use this syntax and can't remember now whether support for it was removed, or if it just withered away. At any rate, if I use the #+header: syntax then I can get the example working partially. It is possible then to get the OP's desired result with the #+call: line. Changing (sbe ...) to (org-sbe ...) in the table calculates the mean, but doesn't yield a real table. The initial "|" on the last line is missing. #+NAME: tbl-example-data #+BEGIN_SRC R :results value runif(n=5, min=0, max=1) #+END_SRC #+RESULTS: tbl-example-data | 0.850588989211246 | | 0.138243367196992 | | 0.382761054905131 | | 0.00688096368685365 | | 0.394350948277861 | #+NAME: R-mean #+header: :var x="" #+header: :results output #+BEGIN_SRC R colMeans(x) #+END_SRC #+call: R-mean(x=tbl-example-data) #+results: : V1 : 0.4273072 #+tblname: summaries | mean | |------| | V1 | 0.2574993| #+TBLFM: @2$1='(org-sbe "R-mean" (x "tbl-example-data()")) hth, Tom -- Thomas S.
