r - Showing code chunk name in output in RMarkdown -


as known in rmarkdown code chunks can named this:

```{r chunkname}  plot(x,y)  ```

is possible showing chunkname in output document?

you can use knitr::opts_current$get()$label

example:

```{r cars} library(knitr) opts_current$get()$label plot(cars) ```

it work outside of chunk, in inline r code. output label of last chunk.

you can of course save labels in vector use them later, instance custom hook:

```{r knitr_setup} library(knitr) ll <- opts_current$get()$label knit_hooks$set(label_list = function(before, options, envir) {     if(before) ll <<- c(ll,opts_current$get()$label) }) opts_chunk$set(label_list=true) ```

ll contain list of chunk labels. however, cannot access names of chunks not yet ran.
