Exporting output and graphics from R

Exporting output and graphics from R

[SabreWolfy]

When the following code is evaluated or exported, only the link to
"testout.png" appears in the RESULTS section.

--8<---------------cut here---------------start------------->8---
#+BEGIN_SRC R :results output graphics :file testout.png :exports both
plot(1:10, 1:10)
x <- 1:10
library(ascii)
options(asciiType = "org")
ascii(x)
#+END_SRC
--8<---------------cut here---------------end--------------->8---

When this code is evaluated, the value of "x" appears in the RESULTS:

--8<---------------cut here---------------start------------->8---
#+BEGIN_SRC R :results output :exports both
x <- 1:10
library(ascii)
options(asciiType = "org")
ascii(x)                                                                      
#+END_SRC    
--8<---------------cut here---------------end--------------->8---

How can I get the first example to output both graphics and ascii output?
I'm using Org 7.9.2.

Removing `output' here should solve the above point.

AFAICT, you can't have both at the same time. Do you have a real use case for
this?

If really needed, you can define your code once, wrap it with some value for
the ":results" header, and "copy" it somewhere else via Noweb's facility,
where it can be evaluated under other values for the ":results" header.

Try upgrading now to Org 8 so that you fiddle only once with the export
variables -- which changed, even if similar, between Org 7.9 and Org 8.

Not directly, But I used the following approach to include pdf as well
as jpeg ion a document.

You simply have to create your graph in R and then include a link in org
manually:

,----
| #+BEGIN_SRC R :results output :exports both
| png("testout.png")
| plot(1:10, 1:10)
| dev.off()
| x <- 1:10
| library(ascii)
| options(asciiType = "org")
| ascii(x)          
| #+END_SRC
| 
| 
| [[./testout.png]]
`----

you will get the code, result (output) and the graph (tested on export
to pdf).

Cheers,

Rainer

There are many ways to kill a bird - but you are right - this one is
nicer. You could even use an org variable to specify the file name.

Maybe I'm not using the right tool for the job. I thought it would be useful
to be able to intersperse explanatory text with output:

--8<---------------cut here---------------start------------->8---
All crows are black. We know this from looking at crows. I analyzed a
dataset using this code, and produced a graph as follows:

#+BEGIN_SRC R :results graphics :file testout.png :exports both
# load data, analyze, make graph
#+END_SRC

The above analysis shows that all crows are black. A table of observed
results is as follows:

#+BEGIN_SRC R :results
# more R code using the same dataset
# will only work if the dataset is loaded again
#+END_SRC

This can be summarized with the following results:
#+BEGIN_SRC R :results graphics :file testout.png :exports both
# R code plotting another graph and showing another output table
#+END_SRC
--8<---------------cut here---------------end--------------->8---

My idea is that I would like the R code included for my reference when
reading the document. I would also like the explanatory text, etc. included,
as well as the output and results for the people who will be reading the
document.

Easier just to do it all in LaTeX directly? But then the code is not live,
like it is in Org.

Thanks. This is a great suggestion.

                          ^^^^^^^^^^^^^^^^^^^^^^^
because you don't use the ":session" header argument. Look at it.

Use ":noweb yes" and references to named code blocks.

Of course, that's the whole point of using Org + Babel. Thanks Eric and Dan,
once again...

N/A
