R，簿记 package，强制 LaTex 进入 ZE1E1D3D40573127E9ZEE0408 块

Question

I'm writing a bookdown that should render both in HTML and PDF, so in some places i've got a chunk like:

{r echo=FALSE, results='asis'}

if(knitr::is_html_output()) {

  cat("
      text with HTML coding, as <br> etc.
")} else {

  cat("
      \\begin{flushleft}
      left aligned text with LaTex coding, as \\break. 
      \\end{flushleft}
")}

Sometimes (i think) Pandoc gets it wrongly and adds \textbackslash before my LaTeX codes (i can see that in.tex file) and it goes literal.

I know a can use LaTeX chunks {=latex} in order to avoid that. But since i'm already in a R chunk, how do i force Pandoc to understand LaTeX?

Answer 1

knitr::raw_latex() instead of cat() did the trick.
