As can be expected, the script is written in JavaScript. I’m proposing a script to add an invisible TOC as metadata to a PDF document during its conversion from Markdown. But clicking on the links doesn’t do anything. That means: The TOC is visible, and it seems to contain links to the headlines. Without R Markdown, the user would need to compute the mean and median, and then report it manually.Some time ago, a forum participant noted that the PDF generated from a Markdown document in DT doesn’t contain a usable table of contents (TOC). We may want to explain in words, that the mean of the length of the petal is a certain value, while the median is another value. For instance, suppose we work on the iris dataset (preloaded in R). It is often the case that, when writing interpretations or detailing an analysis, we would like to refer to a result directly in our text. Ordered list, item 2īefore going further, I would like to introduce an important feature of R Markdown.
