Internal links in rmarkdown don't work

Question

I use rmarkdown to render pdf documents. Now I want to add internal links in the texts.

In the helping pages of rmarkdown, it says an internal link is defined as:

See the [Introduction](#introduction). 

When I Use e.g. the next code there should be two internal links: link1 and link2. Both don't link. Is there something obvious that I am doing wrong? Many thanks in advance!

You're not setting the anchors correctly.

Try the following:

# start  ```{r results="asis",tidy=FALSE,eval=TRUE} cat("click here: [link1](#test1)") ```  click here: [link2](#test1)  \pagebreak  # test 3 {#test3}  \pagebreak  #test 2 {#test2}  \pagebreak  #test 1 {#test1}
