r,knitr,pandoc,rmarkdown , Reference to a chunk in Rmarkdown (v2)

## Question:

Tag: r,knitr,pandoc,rmarkdown

After a while using knitr with latex I'm trying Rmarkdown, principallly because the possibility of having multiple outputs make easier the sharing with colleagues.

My problem is how to reference to chunk for figures in Rmd?

in Rnw classically you make \ref{fig:chunk_name}

Is reference to chunk directly supported, in Rmarkdown, or just internal links to sections etc. are supported? In a positive case, how refer to a chunk like the following?

{r my_chunk}
attach(mtcars)
plot(wt, mpg)



Edit This is the header, I need something more?

Ok the problem was in the knitr formatting options, because it lacks of fig.cap ="", which is needed by Latex to build a figure environnement.

Because of my first try with Rmarkdown I thought the problem was that hyperref was not supported (it was evidently not supported in markdown v1), or to other things related to my newbie use of markdown...

I'm sorry, I was crazy for nothing.

The problem was in the lack of fig.cap in the options so, this works:

{r my_chunk, fig.cap = ""}
attach(mtcars)
plot(wt, mpg)



see fig \ref{my_chunk}
