Hello all,

Please could someone show me how to get an org link to the file in the
results when using #+call with an R source block?

This is the test I am using:

#+source: foo()
#+begin_src R :file bar.png
plot(1,1)
#+end_src

#+results: foo()
[[file:bar.png]]
( so that works fine )

#+call: foo[:file baz.png]()

#+results: foo[:file baz.png]()
: baz.png
( but I wanted [[file:baz.png]] there )

I'm using the commit 1495bc6 of 12th December.

Thank you,

Myles

This works but I have to repeat the filename:

#+call: foo[:file baz.png]() :file baz.png

#+results: foo[:file baz.png]()
[[file:baz.png]]

Hi Myles,

Currently I believe the best option is the solution you posted below,
the file name is repeated because both the code block and the call line
need to know the file name to create the file and the link respectively.

Cheers -- Eric

Thanks for your answer Eric.  Recent changes as per
http://thread.gmane.org/gmane.emacs.orgmode/35396
means that this no longer works.

To recap: what I would like to do is to #+call an R source
block, passing a filename, and have it write a plot to that file and
also insert a link to that file in the org file.  Any ideas?

Here is what I have tried:

#+source: foo()
#+begin_src R :file bar.png :results graphics
plot(1,1)
#+end_src

#+call: foo[:file baz.png]()

#+results: foo[:file baz.png]()
: baz.png

baz.png contains a plot, but no file link is inserted.

#+call: foo()

#+results: foo()
: bar.png

bar.png contains a plot, but no file link is inserted.

#+call: foo[:file biff.png]() :file biff.png

#+results: foo[:file biff.png]()
[[file:biff.png]]

a file link is inserted but file biff.png contains 'biff.png'

#+call: foo[:file pow.png]() :file pow.png :results graphics

#+results: foo[:file pow.png]()
[[file:pow.png]]

a file link is inserted but file pow.png contains 'pow.png'

Thanks,

Myles

Thanks for bringing this up Myles.

Yes you need :results file, so the line should be

#+call: foo[:file baz.png]() :results file

Explanation: In simple single-block usage, :file automatically
sets :results file. But here :file in square brackets is passed to block
foo, so the #+call line needs its own :results file. (And in fact :file
would be wrong; see below).

Yep. Same as above, except here you haven't overridden the file name.

> [[file:biff.png]]

Right, this one's kind of instructive for understanding this
stuff. Here, foo returns its file name as a string, so
"biff.png". The #+call line has been told to send its results to file
with the :file argument, and it takes that literally, writing the string
"biff.png" to its output file. So if what we want is a file containing
graphics, we are not going to want :file on the #+call line. What we
want is to interpret the string as a file name, and that's what :results
file does.

Same as above. #+call receives a string from foo; it can't turn that
string into the desired graphics. In fact, :results graphics currently
only has any effect on an R block (i.e. at an R block, or passed to an R
block inside [ ... ]).
