You can label chapter and section titles using {#label}
after them, e.g., we can reference Chapter \@ref(intro). If you do not manually label them, there will be automatic labels anyway, e.g., Chapter \@ref(methods).
Figures and tables with captions will be placed in figure
and table
environments, respectively.
par(mar = c(4, 4, .1, .1))
plot(pressure, type = 'b', pch = 19)
(\#fig:nice-fig)Here is a nice figure!
Reference a figure by its code chunk label with the fig:
prefix, e.g., see Figure \@ref(fig:nice-fig). Similarly, you can reference tables generated from knitr::kable()
, e.g., see Table \@ref(tab:nice-tab).
knitr::kable(
head(iris, 20), caption = 'Here is a nice table!',
booktabs = TRUE
)
Table: (#tab:nice-tab)Here is a nice table!

You can write citations, too. For example, we are using the bookdown package [@R-bookdown] in this sample book, which was built on top of R Markdown and knitr [@xie2015]. ddd aaa
