Use Docker Images to Process Rmarkdown Blocks
Gives you the ability to use arbitrary Docker images
(including custom ones) to process Rmarkdown code chunks.

Creation of Lightweight Docker Images for Your Packages
person(given = "Lars",
family = "Kjeldgaard",
role = c("aut", "cre"),
email = "lars_kjeldgaard@hotmail.com")
Build a lightweight Docker r-base container image for your R
package, in which the package itself is available. The Docker image seeks
to mirror your R session as close as possible with respect to R specific
dependencies. Both dependencies on CRAN R packages as well as local non-CRAN
R packages will be included in the Docker container image.

Functions to convert 'Microsoft Word' or 'Microsoft PowerPoint'
documents to 'PDF' format and also for converting them into a thumbnail.
In order to work, 'LibreOffice' must be installed on the machine and
possibly 'python' and 'Microsoft Word'. If the latter is available,
it can be used to produce PDF documents identical to the originals,
otherwise, 'LibreOffice' is used.
