Hi Thomas,
In the example below, note that the R representation of the
directory listing
escapes the quotes in the original and encloses it all in a second
set of
quotes, e.g. "\"theta-1.csv\"".
This must come up a lot. Is there an idiomatic way to change
"\"theta-1.csv\"" to "theta-1.csv" so that it could be assigned to
x and the
following statement would yield a valid path?
afile <- paste("r/",x,sep="")
I'm aware the answer might be R code, but it is to tightly tied to
org-
babel I figure it makes sense to ask the question here.
I already sent an email related to double quotes in result tables.
See the
email hereunder.
In order to get a result table without the double quotes for all
texts, I use
the patch enclosed in my email and add the ":results noquotes" header
parameter.
In your example, I would get the following result:
--8<---------------cut here---------------start------------->8---
#+srcname: thetas()
#+begin_src shell :results noquotes
cd r && ls theta*
#+end_src
#+results: thetas
| theta-1.csv |
| theta-2.csv |
--8<---------------cut here---------------end--------------->8---
Is this what you need?
Here's the email I sent a few days ago. It contains the patch I use
to remove
the double quotes when I need it:

Hi,
Often, I find useful that babel could generate result tables without
the
double quotes (") enclosing all the text values in the cells.
In order to do that, I added a 'noquotes` option to the :results
header
argument.
Here's my patch. As I'm not an elisp expert, please tell me if
there's a
better/safer way to do that or maybe that it already exists an
option to do
that...
