I have a R code src block in a org file. When exported to html, the R code is correctly syntax highlighted. But when exported to pdf(latex), the R code is not highlighted. I found this thread
https://lists.gnu.org/archive/html/emacs-orgmode/2010-07/msg00379.html which suggests setting the variable
org-export-latex-listings. This variable seems no longer exist in Org 8.2.6. What variables shall I set so that the R code is syntax highlighted when exported to pdf in Org mode 8.2.6? Thanks.
