To add myClass to source chunk: “`{r cars, class.source=”myClass”} summary(cars) “` Previous answer that inspired the class.source options (see here) You can add a class using the fenced_code_attributes pandoc’s extension … Read more
Go into RStudio and find the system environment variable for RSTUDIO_PANDOC Sys.getenv(“RSTUDIO_PANDOC”) Then put that in your R script prior to calling the render command. Sys.setenv(RSTUDIO_PANDOC=”— insert directory here —“) This worked for me after I’d been struggling to find how rmarkdown finds pandoc. I had to check github to look at the source.

So, pandoc does not parse the content of latex environments, but you can fool it by redefining the commands in your header.tex file: \usepackage{lscape} \newcommand{\blandscape}{\begin{landscape}} \newcommand{\elandscape}{\end{landscape}} Thus, here \begin{landscape} is redefined to \blandscape, and \end{landscape} to \elandscape. Using those newly defined command in the .Rmd file seems to work: — title: “Mixing portrait and landscape” … Read more
