Hello,

I would like to use :prologue  and epilogue with latex output when using
R. Would it be possible to do something like the following?


#+NAME: test1123
#+BEGIN_SRC R :results output latex :prologue \\begin{table} :epilogue \\end{table} :session *R* :dir tmp :cache no
print(xtable(data.frame(a=rnorm(10),b=letters[1:10])),floating.environment=FALSE)
#+END_SRC



#+RESULTS: test1123
#+BEGIN_EXPORT latex
Error: unexpected input in "\"
% latex table generated in R 3.3.1 by xtable 1.8-2 package
% Mon Apr 24 12:40:21 2017
\begin{FALSE}[ht]
\centering
\begin{tabular}{rrl}
  \hline
 & a & b \\ 
  \hline
1 & -0.79 & a \\ 
  2 & 0.71 & b \\ 
  3 & 0.82 & c \\ 
  4 & 1.04 & d \\ 
  5 & 0.46 & e \\ 
  6 & 1.02 & f \\ 
  7 & 0.89 & g \\ 
  8 & -1.12 & h \\ 
  9 & 0.77 & i \\ 
  10 & 2.08 & j \\ 
   \hline
\end{tabular}
\end{FALSE}
Error: unexpected input in "\"
#+END_EXPORT


Best wishes,

Jeremie

Sure. But you do not need to; see my comment at bottom.  Try this:

#+NAME: test1123
#+HEADER: :prologue cat("\\begin{table}\n")
#+HEADER: :epilogue cat("\\end{table}\n")
#+BEGIN_SRC R :results output latex  :session *R* :dir tmp :cache no
require(xtable)
print(xtable(data.frame(a=rnorm(10),b=letters[1:10])),floating.environment=FALSE)
#+END_SRC

You might be better off using the :post header arg.

Define a src block like this:

#+name: add-table-env
#+BEGIN_SRC emacs-lisp
(format "\\begin{table}\n%s\n\\end{table}\n" *this*)
#+END_SRC

Then use

#+HEADER: :post add-table-env()

in place of the two header lines above.  The advantage is that you can if 
you want do more complicated moidification of the result.

AFAIK, LaTeX has no FALSE environment.

I think what you actually wanted was *not* :prologue and :epilogue but 
this R code:

#+begin_src R
print(xtable(data.frame(a=rnorm(10),b=letters[1:10])),floating.environment="table")
#+end_src


HTH,

Chuck
