I'm interested in creating versioned Docker images of Bioconductor releases back to 3.6 for unit testing against my package code. I'm stuck getting Bioconductor 3.7 to install instead of 3.8 on R 3.5 using a rocker/r-ver base image (e.g. R 3.5.3). What's the correct approach for this? Both BioC 3.7 and 3.8 are pinned against R >= 3.5.0. Otherwise, I'm good to go creating images for BioC 3.6, 3.8, and 3.9.
BiocManager::install(version = "3.7") doesn't work.
