Possible bug in bookdown when compiling to PDF. Images get cut by the margins

When I compile my Bookdown books for pdf output I get figures cut by the left and right margins. This does not happen if I generate them with ggsave() myself and then add them with knitter::include_graphics().

    ---
    output:
      pdf_document: default
      html_document: default
    ---

    # Example
    ```{r example, message=FALSE}
    require(tidyverse)
    ggplot(data=iris, aes(x=Sepal.Length, y=Sepal.Width))+geom_point()
    ```

I execute `bookdown::render("index.Rmd", output_format=pdf_book(keep_tex=TRUE))

I get this image as output (in main_files/figure-latex)

Image I get, it is cut by the margins

Is this a bug or is it just me? How can I solve it? I do not like very much the idea of ggsave() + knitr::include_image(), but it is the only workaround I got so far.

If you take a look at the fig_crop argument on the help page ?rmarkdown::pdf_document, you will see that figure files will be cropped by default if pdfcrop is available. You can turn this feature off via:

output:
  pdf_document:
    fig_crop: false
