Centering image and text in R Markdown for a PDF report
If you are centering the output of an R code chunk, e.g., a plot, then you can use the fig.align option in knitr.
```{r fig.align="center"}plot(mtcars)```
I had the same question. I have tried all solutions provided above and none of them worked... But I have found a solution that works for me, and hopefully for others too.
<center></center>This code will center both the image and the caption. It is essential that you leave lines between <center>, the image code, and </center>, otherwise the image will be centered but the caption will disappear.
If you want your image to have a clickable link, you can embed things like
[](www.link_to_image.com)However, the caption will no longer appear.
So if you want a clickable caption you will have to do it in two steps:
<center>[your image caption](www.link_to_image.com)</center>Same here, make sure there are empty lines in between each command ones. If you want both the image and the caption to be clickable, then combine the middle and the last codes above. I hope this helps a bit.
You can use raw LaTeX in R Markdown. Try this:
\begin{center}Text\end{center}There is, of course, a catch: everything between begin{...} and \end{...} is interpreted as raw LaTeX by Pandoc, so you can't use this technique to center the output of R code chunks, or Markdown content.
