Because Babel is not able to remove the old results of "raw" output as
the output has no obvious delimiters. However "org" output should be

Getting a bit of odd behavior on LaTeX export. Here's the gist of my
block below. I've iterated through various model parameters and saved
the results to filenames based on those parameters. These are stored
in a vector =filenames=.
#+begin_src R :session model :results output raw :exports results
for(i in 1:nrow(filenames)) {
# insert section header
cat(paste("*Param1 = ", as.character(params[i, 1]),
"; Param2 = ", as.character(params[i, 2]),"*", sep=""))
cat("\n\n")
cat("#+begin_center")
cat("\n")
read.csv(filename)
for(j in 1:5) {
ggplot code
pdf(output-filename)
print(p)
dev.off()
cat(paste("[[../plots/",output-filename,"]]",sep=""), sep="\n")
cat("\n")
} # end plotting loop
cat("#+end_center")
cat("\n\n")
} # end filename cycling loop
#+end_src
I get results like so:
#+RESULTS:
*Param1 = 4; Param2 = 0.025*
#+begin_center
[[../plots/filename1.pdf]]
[[../plots/filename2.pdf]]
[[../plots/filename3.pdf]]
[[../plots/filename4.pdf]]
[[../plots/filename5.pdf]]
#+end_center
There are six of these sections, however when I do C-c C-c on the
block and then C-c C-e p to export to LaTeX, I get duplicate sections
back to back. I have to delete the entire results section and only do
C-c C-e p with an empty results section to have the duplicate removed.
Why might this be?

Disregard again... adding multiple newlines with cat() doesn't work,
but I had the idea to do:
cat(paste("[[../plots/",filename,"]]",sep=""), sep="\n")
cat("\n")
Works great. I suppose I can use this to add #+attr_latex options as
well as captions. Cool stuff.

Disregard the previous. I found that I should be using cat(paste(...))
instead of print(), since that removes the [1] from each line.
Unfortunately,
,---
| cat(paste("[[../plots/",filename,"]]",sep=""), sep="\n\n")
`---
still gives me output in orgmode of filenames with no new lines in
between so my plots are being printed 4-up on a page (2 wide, 2 tall)
instead of only 1 wide and 2 tall. If I manually enter new lines in
between the output file names, they behave as they should. How do I
get org to accept the extra newlines I'm trying to add? Executing in
the R session itself behaves as expected and does space the lines.

Trying this, but am hung up on directing to STDOUT. I tried just using:
,---
| print(paste("[../plots/",filename,"]",sep=""))
`---
but just ended up with a bunch of strings in the pdf output. In
googling around I found this on SO:
-
http://stackoverflow.com/questions/4112896/how-can-i-redirect-r-warning-messages-to-stdout
So I tried:
,---
| sink(stdout(),print(paste("[../plots/",filename,"]",sep="")))
`---
But nothing gets printed into pdf at all.
---
Actually, I revisited the above plaint print() statement to see what's
going on and the #+results block contains files like so:
,---
| [1] "[../plots/filename.pdf]"
`---
How do I strip the [1] and the quotes?

Have you tried using header arguments like the following.
:results output raw :exports results
and then printing the file names (including the Org-mode link syntax) to
STDOUT from within your R code block.
If I understand correctly that should result in the behavior you're
after.

[O] Including multiple plots resulting from a loop of R code in LaTeX
I'm conducting some neural network analysis, and the results are
highly dependent on the random seed set prior to creating the model. I
loop through seeds 1-500, storing the predicted values in one data
frame and a table of mean sum of squared errors in another table.
Then, I use ggplot to create only the 10 or so plots with the lowest
error. The loop is something like this:
--
for(i in 1:10) {
filename <- paste("neuralnet-","-seed-",as.character(mse[i,1]),".pdf", sep="")
pdf(filename, width=12, height=8)
[ggplot code]
dev.off()
--
What I want to know is how to include the resultant files in LaTeX
export. Since my model runs and then sorts by error, I don't know
which seeds produce the best files beforehand, so I'd have to look at
the error table and manually insert the plot names by hand. Changing
results means changing file names by hand again.
Any suggestions for things like this where the output of a babel block
is not a single file?
Thanks,
John
