Hi

I do the following to create a graph in R and then convert / copy / do other stuff with it in the
bash shell:

#+header: :results graphics
#+header: :file Test.pdf
#+header: :width 4
#+header: :height 8
#+header: :pointsize 8
#+begin_src R
  plot(runif(100))
#+end_src

#+BEGIN_SRC sh :session shell
  cp Test.pdf Test2.pdf
#+END_SRC


Is there a way of automatically giving the ffile name from the :file parameter tio the second code
block, so that I just have to change the :file argument when I want a different name for the graph?

Thanks,

Rainer

Hi Rainer,

I am not aware of any possibility to pass the :file parameter from one
code block to another.  But for your use case, the file name is also
the return value of the R code block.  So, you can do:

#+name: mypdfplot
#+header: :results graphics
#+header: :file Test.pdf
#+header: :width 4
#+header: :height 8
#+header: :pointsize 8
#+begin_src R
  plot(runif(100))
#+end_src


#+BEGIN_SRC sh :session shell :var mypdf=mypdfplot()
  cp "$mypdf" Test2.pdf
#+END_SRC

Best,
Andreas

Looks absolutely perfect. Thanks a lot,
