Prevent pagebreak in kableExtra landscape table

Question

How can a landscape table be plotted in R Markdown (PDF output) without causing a page break to be inserted?

There is the function landscape from the kableExtra package, but this forces a page break to be inserted.

Example:

The normal behaviour for tables in R Markdown is that the will float to minimise the breaking up of text.

You can use the LaTeX package realboxes to do what you want

title: "Mixing portrait and landscape"
output: pdf_document
header-includes:
  - \usepackage[graphicx]{realboxes}
  - \usepackage{booktabs}
---

Some text

\Rotatebox{90}{
```{r, echo=FALSE, warning=FALSE}

knitr::kable(mtcars, "latex", booktabs = TRUE)
```
}

This produces a single page pdf with the table presented in landscape. The problem with this approach is that it does not seem to work with a caption.

Edit You can use the caption latex package to add the caption

title: "Mixing portrait and landscape"
output: pdf_document
header-includes:
  - \usepackage[graphicx]{realboxes}
  - \usepackage{booktabs}
  - \usepackage{caption}
