AFAICT, this variable has no effect on export of calls to R source code
blocks, where the source code block is set with :results raw.

Also, AFAICT, the behavior of R source code blocks differs from others,
including shell.

With the default value of org-babel-inline-result-wrap I get this LaTeX
export:

  \section{Export this subtree raw to \LaTeX{}}
  \label{sec-1}
  Will shell-2 export 2 with a newline?

  Will r-2 export 2 with a newline?

  Will shell-2-raw export 2 with a newline?

  Will r-2-raw export 2
   with a newline?
  \section{Export this subtree without raw to \LaTeX{}}
  \label{sec-2}

  Will shell-2 export \texttt{2} with a newline?

  Will r-2 export \texttt{2} with a newline?

  Will shell-2-raw export \texttt{2} with a newline?

  \begin{verbatim}
  Will r-2-raw export 2
  \end{verbatim}
  with a newline?
  % Emacs 24.3.1 (Org mode 8.2.5h)

With org-babel-inline-result-wrap set to "%s" I get this:

  \section{Export this subtree raw to \LaTeX{}}
  \label{sec-1}
  Will shell-2 export 2 with a newline?

  Will r-2 export 2 with a newline?

  Will shell-2-raw export 2 with a newline?

  Will r-2-raw export 2
   with a newline?
  \section{Export this subtree without raw to \LaTeX{}}
  \label{sec-2}

  Will shell-2 export 2 with a newline?

  Will r-2 export 2 with a newline?

  Will shell-2-raw export 2 with a newline?

  \begin{verbatim}
  Will r-2-raw export 2
  \end{verbatim}
  with a newline?
  % Emacs 24.3.1 (Org mode 8.2.5h)

Note that there is no change in the LaTeX export of the R calls.

I think this is a bug in ob-R.el.  From my experiments, it behaves
differently than the other babel languages, including shell.

For LaTeX export, the workaround is to avoid :results raw with R source
code blocks. Although a spurious newline is inserted into the source,
this is ignored by LaTeX.

All the best,
Tom
