I have just started using blogdown and I have created a project by using template Hugo-Xmin. In RStudio, when creating the project in blogdown, it created some predefined posts, I am editing this one:
/content/post/2015-07-23-r-rmarkdown.Rmd
Adding a tikz image
Following this question and the bookdown documentation on engines, I modified the afore-mentioned file by adding this snippet:
This is a tikz picture:
```{r, echo=FALSE, engine='tikz', out.width='90%', fig.ext=if (knitr:::is_latex_output()) 'pdf' else 'png', fig.cap='Some caption.'}
\begin{tikzpicture}[scale=.7]
\draw [fill=gray!30,very thick] (0,-1) rectangle (5,1);
\draw [very thick] (5, 0) -- (13,0);
\node [below] at (2,-1) {\large Hello};
\node [below, align=center] at (0,-1) {\large Two\\ lines};
\end{tikzpicture}
```
Failed to process the post
As soon as I save (since I have the serve on), but also when using blogdown::build_site(), I get this:

Troubleshooting
I checked my engines and saw that tikz is actually among them:
> names(knitr::knit_engines$get())
[1] "awk" "bash" "coffee" "gawk" "groovy" "haskell" "lein" "mysql"
[9] "node" "octave" "perl" "psql" "Rscript" "ruby" "sas" "scala"
[17] "sed" "sh" "stata" "zsh" "highlight" "Rcpp" "tikz" "dot"
[25] "c" "fortran" "fortran95" "asy" "cat" "asis" "stan" "block"

[41] "lemma" "corollary" "proposition" "conjecture" "definition" "example" "exercise" "proof"
[49] "remark" "solution"
The documentation said that some engines are shipped in bookdown and not knitr, but I can see tikz is there! So I have the engine, but still I cannot use it. What am I doing wrong?
