Changing the default RMarkdown font

Question

I am struggling with changing the font of my pdf files. I don't have Helvetica on my computer so I am unable to compile .pdf (html works perfectly). I believe my Rmarkdown coding is not working but it is identical to what is suggested here. LaTeX is installed and properly working, I can compile using XeLaTeX from Lyx.

  pdf_document:
    latex_engine: xelatex
sansfont: Calibri Light

As far as I understand, Calibri font is loaded

fonts()[grepl('Calibri',fonts())]
[1] "Calibri"       "Calibri Light"

I keep geting the cannot load afm file 'Helvetica.afm' error. This is my session

UPDATE

The error is with R code chunks. If I knit everything but the R chunk it works

this is my test  

I can write anything here and it will render **perfectly**  

```{r}
plot(mtcars)
```

processing file: test.Rmd

And you do have paragraphs that use sansfont? Check if `mainfont: Calibri Light` works... — Martin Schmelzer, Jan 05 '17 at 19:31
`mainfont: Calibri Light` doesn't work I have normal chunks of text if I understand correctly your question. — Matias Andina, Jan 05 '17 at 19:33
Weird, `mainfont: Calibri Light` works for me (with no indentation). — Martin Schmelzer, Jan 05 '17 at 20:07
Try updating your packages (there are new versions for at least `yaml` and `rmarkdown`)... — Martin Schmelzer, Jan 05 '17 at 20:08
@MartinSchmelzer All packages are up to date, still get the error. It is indeed weird, there is something I must not be adding/doing — Matias Andina, Jan 05 '17 at 20:28
only text is able to be compiled, thus errors arise in R code chunks — Matias Andina, Jan 05 '17 at 20:56
Are you using the pdf device to add plots to the document? Try the tikz device instead. — Martin Schmelzer, Jan 05 '17 at 23:10
