Dear list,

Hopefully this is not too basic, nor has been answered before.

I would like to know if there is away to have alll R code blocks in a
document evaluated automatically (i.e. without query) when exporting
to Latex.  Now I have to answer "yes" multiple times to the question
"Evaluate this R code block in your system" every time I do an export,
which is somewhat annoying.
Many thanks,

Julian

See the variable `org-confirm-babel-evaluate'.  Be careful about
unilaterally setting it to nil in case you receive org files with
code blocks from people you don't trust.

Cheers,
Lawrence

Many thanks Lawrence.  Yes, I´m aware of the risks, but for now I am
only working with my own files.
Do you know if it is possible to evaluation confirmation as a header
option, so I can left it on but turn it off in my own files?
Thanks again,

Julian

I don't believe it is.  If you think about, this is also a
security hole, since a malicious user could put the relevant
header in, even if you've set org-confirm-babel-evaluate to t.

Cheers,
Lawrence

Yes, you are right.  For now, I´ll turn confirmation off for R code
only, and keep an eye on .org files from unknown origins.
All the best,

Julian

Indeed this is the case, the :eval header argument [1] can be used
inhibit the evaluation of some code blocks, if the user already has

  (setq org-confirm-babel-evaluate nil)

but it can not be used to remove the need for confirmation of code block
evaluation when the user has

  (setq org-confirm-babel-evaluate t)

For security reasons.

Personally I don't require confirmation of evaluation as I find that I
both trust everyone sharing org-mode files with me, and generally I read
code blocks before I evaluate them.

Best -- Eric

I don't have experience w/ LaTeX export, but try this to turn off the "evaluate
this block?" prompt: (setq org-confirm-babel-evaluate nil)
