Hi Myles, I believe the problem here is that your :var header argument syntax is wrong. A :var header argument must have a name, and equals sign, and an assignment for the variable, e.g.
#+begin_src sh :var name="eric" echo $name #+end_src #+results: : eric Please see the online manual for more information on the :var header argument. http://orgmode.org/manual/var.html#var Best -- Eric Myles English <mylesengl...@gmail.com> writes: > Hello, > > First of all thanks very much for all the very well explained help > given in previous threads I have started. > > Now, I have found different results arise from a difference in position > of parameters (I'm using commit c01c2ad Fri Mar 18, R version 2.12.20, > Feb 25): > > > #+TBLNAME: data > | x | parameter | value | > |---+-----------+-------| > | 0 | heat | 30 | > | 1 | heat | 30 | > > This next block works as I expect and returns the column names: > > #+source: namesNFirst > #+begin_src R :var N :var tbl :var param :colnames yes > names(tbl) > #+end_src > > #+call: namesNFirst(N=10,tbl=data,param="heat") > > #+results: namesNFirst(N=10,tbl=data,param="heat") > | x | > | parameter | > | value | > > Now, I would expect this to return the same result as above: > > #+source: namesNLast > #+begin_src R :var tbl :var param :var N :colnames yes > names(tbl) > #+end_src > > #+call: namesNLast(tbl=data,param="heat",N=10) > > but it doesn't: > > #+results: namesNLast(tbl=data,param="heat",N=10) > | X0 | > | heat | > | X30 | > > Removing the string parameter 'param', and again it works as expected: > > #+source: namesNoParam > #+begin_src R :var tbl :var N :colnames yes > names(tbl) > #+end_src > > #+call: namesNoParam(tbl=data,N=10) > > #+results: namesNoParam(tbl=data,N=10) > | x | > | parameter | > | value | > > I can't find any difference R-side when using :session.
