The docker file found here produces a modified version of the Bioconductor:devel docker image which has TinyTex pre-installed. This allows use to compile the package manual pages and and PDF vignettes during testing. Installing TinyTex and the required LaTeX packages takes approximately 10 minutes on our emulated system, so there is a responsiveness benefit to using an image with it already installed.
An example workflow can be found in .github/workflows/test-package-arm64.yml. This demonstrates how to use the QEMU emulator and the ARM64 Docker image described above, to first install and cache package dependenceies, followed bty running the standard R pacakge tests in a manner similar to the Bioconductor Build System.
The folder examplePKG contains a small R package that is testsed by the example workflow.
