[Orgmode] #+call ?

[Thomas S. Dye]

Aloha all,

I'm expecting to see the file bar.pdf output.

#+srcname: single-date
#+begin_src R :results output :file foo.pdf
  library(ggplot2)
  z <- read.csv(file = x)
  g <-  ggplot(z, aes(x=1950 + cal.BP, y=Posterior.probability))
  g + geom_bar(stat='identity') + xlab("Year AD") +
    ylab("Probability")
#+end_src

#+call: single-date(x="alpha-2.csv") :file bar.pdf :height 4

#+results: single-date(x="alpha-2.csv")
[[file:foo.pdf]]

Also, the :height header argument doesn't have any effect.

I want the single-date source block to be a general function that I  
can call several times from an Org-mode file that I hope to distribute  
as a piece of reproducible research.  There will be separate #+calls  
for each of the graphs in the paper.

Apologies in advance if the answer is obvious.  I'm using Org-mode  
version 7.02trans (release_7.02.37.g52fb)

All the best,
Tom
