How about in the YAML: params: configuration: NULL project_conf: NULL data: NULL
Then in the first chunk something like: ```{r data-config} if(is.null(params$data)){ data(data_ionstar, package = "prolfqua") data = data_ionstar configuration = data$filtered()$config } ``` You can use a more ornate expression for these parameters when rendering otherwise `rmarkdown::render()`, which I suppose you could call from a Makefile if needed when rendering package the vignettes.

By this I can reuse the vignette with a different dataset.
