Hi, I encounter the following problem (org version 8.3.2):
When I have the following R source code block in my org file: #+BEGIN_SRC R :exports results :results replace output latex :eval export library(xtable) print(xtable(matrix(c(1,2,3), nrow=1)), only.contents=TRUE, include.rownames=FALSE, include.colnames=FALSE, comment=FALSE, hline.after=NULL) #+END_SRC and I evaluate it, I get the expected result: #+RESULTS: #+BEGIN_LaTeX 1.00 & 2.00 & 3.00 \\ #+END_LaTeX However, when I also include the =:session *R*= in my header, I get this: #+BEGIN_SRC R :session *R* :exports results :results replace output latex :eval export library(xtable) print(xtable(matrix(c(1,2,3), nrow=1)), only.contents=TRUE, include.rownames=FALSE, include.colnames=FALSE, comment=FALSE, hline.after=NULL) #+END_SRC #+RESULTS: #+BEGIN_LaTeX #+END_LaTeX I.e., no result. However, when evaluating the code in R it works (i.e., R prints out =1.00 & 2.00 & 3.00 \\=). I need to have =:session *R*= in the header because I want to print results of previous calculations in R. I would like to not have =\hlines= in my LaTeX output (I integrate the result into a LaTeX table). This problem does not occur when I set =hline.after= to a non-NULL value, e.g.: #+BEGIN_SRC R :session *R* :exports results :results replace output latex :eval export library(xtable) print(xtable(matrix(c(1,2,3), nrow=1)), only.contents=TRUE, include.rownames=FALSE, include.colnames=FALSE, comment=FALSE, hline.after=1) #+END_SRC #+RESULTS: #+BEGIN_LaTeX 1.00 & 2.00 & 3.00 \\ \hline #+END_LaTeX Thanks!
