Cross-reference To Figure In R Markdown With Html Output Is Not Working

I would like to show a nice cross-reference to a picture in the HTML document I'm creating with R Markdown. However, even if I followed the bookdown section on cross-references, I

Solution 1:

I'm not sure. But are you using bookdown? If you follow https://bookdown.org/yihui/bookdown/get-started.html, and use bookdown project as in https://github.com/yihui/bookdown-minimal. Then you should get the result you want.

For example, I use https://github.com/yihui/bookdown-minimal and modify the index.Rmd to something like this, and the cross reference shows correctly.

--- title: "A Book" author: "Frida Gomam" site: bookdown::bookdown_site documentclass: book output: bookdown::gitbook: default bookdown::pdf_book: default ---

{r foo, fig.cap="$f_{p}$ as a function of $g$ for various values of $r=\\frac{\\rho_{w}}{\\rho_{a}}$", echo=FALSE} # All defaults knitr::include_graphics("download.png")

 A cross-reference to figure \@ref(fig:foo).

Update: Modify the output field to bookdown::html_document2 seems to generate the html document similar to rmarkdown::html_document.
