RMarkdown is not referencing tables

Question

Somehow my RMarkdown document is not crossreferencing tables or figures. Here is a stripped down version of my document.

---
title: "Test"
author: "Me"
date: "01/04/2022"
output: bookdown::pdf_document2
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)

var1<-sample(LETTERS)
tab1<-table(var1)

My table is in Table \@ref{tab:tab1}

library(knitr)
kable(tab1, caption="my table")

AS we see in Figure \@ref{fig:plot1}

plot(seq(1,10,1))

Answer 1

You should call your tab1 in the code chunk like this {r tab1}. And use () instead of {} for your @ref. In that case it reference to your figures and tables. You can use the following code:

---
title: "Test"
author: "Me"
date: "01/04/2022"
output: bookdown::pdf_document2
---

My table is in Table \@ref(tab:tab1)

```{r tab1, echo =FALSE}
var1<-sample(LETTERS)
tab1<-table(var1)

library(knitr)
kable(tab1, caption="my table")
```

\newpage

AS we see in Figure \@ref(fig:plot1)

```{r plot1, fig.cap ="plot", echo=FALSE}
par(mar = c(4, 4, .2, .1))
plot(seq(1,10,1))
```

Output:

As you can see on the image, when you click on 1 in will go to your table.
