RMarkdown pdf document chunk output exceeds page margins

Question

While I am knitting a document as a PDF using RMarkdown some code chunk outputs exceeds the page margins as seen on the pic.

Any ideas to fix this?

Answer 1

Many functions do not respond correctly to the page size config. So to solve such an issue, you have to include the following configuration for the output file.

output: 
  pdf_document:
    pandoc_args: --listings
    includes:
      in_header: preamble.tex

create the file preamble.tex in the same folder where the Rmarkdown file exists, and its content is the following:

\lstset{
  breaklines=true
}
