Hi All: In creating a R Notebook I know that in the text I can link to a (sub) section by using the command: [Header 1](#anchor) and putting the appropriate anchor name at the appropriate header. But can the same be done for code chunks, if the code chunk is named? What I want to do is say that such and such code chunk is an example of how to do something, and have that link to the appropriate code chunk. Thanks for any help. -Roy ********************** "The contents of this message do not reflect any position of the U.S. Government or NOAA." ********************** Roy Mendelssohn Supervisory Operations Research Analyst NOAA/NMFS Environmental Research Division Southwest Fisheries Science Center ***Note new street address*** 110 McAllister Way Santa Cruz, CA 95060 Phone: (831)-420-3666 Fax: (831) 420-3980 e-mail: Roy.Mendelssohn at noaa.gov www: http://www.pfeg.noaa.gov/ "Old age and treachery will overcome youth and skill."

You are sadly confusing R Notebooks with other knitr-based processing formats such as bookdown/LaTeX, as I have in the past. The features available for cross-referencing are strongly tied to the underlying handling of knitr output. This area of "knitr" functionality is a recurring area where new users I have shown knitr to complain of a bait and switch and often wander away as it clearly is not a write-once-output-many tool. But if you are willing to drop the Notebook idea then bookdown is not bad. There is also a distinct lack of R content in this posting... -- Sent from my phone. Please excuse my brevity.

Although it is not an elegant solution, but if your output format is HTML, you can add an arbitrary empty HTML element like <span id="foo"></span> before your code chunk. Then you can jump to this <span> via a link like "see [this code chunk](#foo)".

Thanks. I will try that and see if I can get it to work. I am working on a vignette for a package. I should have been more careful in my wording, it was really a RMarkdown question, not specifically an RNotebook question. I will leave to others to decide if that implies R content, I am just grateful for the help. -Roy> On Aug 29, 2017, at 2:52 PM, Yihui Xie <xie at yihui.name> wrote: > > Although it is not an elegant solution, but if your output format is > HTML, you can add an arbitrary empty HTML element like <span > id="foo"></span> before your code chunk.
