No patch is needed.
The point of the code in org-babel-R-assign-elisp is to create a data.frame
when `value' is a list.
The patch adding `unlist(res)' turns it into an ordinary vector.
This will break almost all uses of :var in R scr blocks.
I don't think this example could have worked for a long while - turning
elisp lists into R data.frames has been a feature for a good while.
Also, note the use of `sbe' vs `org-sbe' in the formula.
#+TBLFM: @2$1='(sbe "R-mean" (x "tbl-example-data()"))
Use `colMeans(x)' to fix the worg page.
HTH,
Chuck
