    The key is BiocManager::repositories(), which determines the repositories where R looks for packages. R choose the first repository where it finds the package (maybe of equivalent version, not exactly sure...). The first argument to repositories() can be a site repository, so
    > BiocManager::repositories("https://ima.repo")
    The Bioc repositories themselves are based on getOption("BioC_mirror") and getOption("repos"), so 
    > options(BioC_mirror = "https://a.mirror.org")
    > BiocManager::repositories()
    These can be file paths; we are just delegating to install.packages().
    It sounds like this doesn't work, somehow for you. Can you elaborate?

        Dear all,
        I like the new BiocManager package with its new possibilities to install specific versions of Bioconductor - but what I miss is the possibility to specify a local Bioconductor mirror from which to install packages. 
        Our calculation clusters don't have direct internet access, so I am mirroring CRAN and Bioconductor to local folders that are accessible by the cluster. Previously, with BiocInstaller and biocLite.R, I could install packages from these simply setting options(repos = "<path to local CRAN dir>") and options(BioC_mirror = "<path to local BioC dir>"). Now, with BiocManager this does no longer work. Is it possible to specify a local mirror for BiocManager? And if not - would it be possible to add this possibility?
