This will create a basic Dockerfile based on rocker/verse
use_dockerfile(pkg = ".", rocker = "verse", rmd_to_knit = "path_to_rmd")defaults to the package in the current working directory
chr, the rocker image to base this container on
chr, path to the Rmd file to render in the Docker container, relative to the top level of the compendium (i.e. "analysis/paper/paper.Rmd"). There's no need to specify this if your Rmd to render is at "analysis/paper/paper.Rmd", "vignettes/paper/paper.Rmd" or "inst/paper/paper.Rmd". If you have a custom directory structure, and a custom file name for the Rmd file, you can specify that file path and name here so Docker can find the file to render in the container.B
