This code chunk will extract all code blocks from `example.Rmd` and write them to a temporary file, preservining chunk options. It will then read them and make those chunks avaliable in the current R environment when the presentation is knitted. | |
```{r include, eval=TRUE, echo=FALSE, include = FALSE} | |
tmp_script <- tempfile() | |
knitr::purl("example.Rmd", output=tmp_script, quiet = TRUE) | |
knitr::read_chunk(tmp_script) | |

We can then include a chunk from `example.Rmd` like so: |
