Not that it solves your problem per se, but here's what I think CRAN
only has rtracklayer 1.48.0 installed on WIndows, i.e. why you get
error "namespace 'rtracklayer' 1.48.0 is being loaded, but >= 1.51.5
* The current Bioconductor "release" is version 3.12
* As you say, Bioconductor 3.12 provides rtracklayer 1.50.0
* However, if you look at that page, for Windows it only provides
rtracklayer 1.49.5 (this is because rtracklayer never successfully
checked on Bioconductor 3.12)
* Since the minor version component of rtracklayer 1.49.5 is _odd_, it
means it's from a Bioconductor 'devel' branch, i.e. when Bioconductor
3.12 was in devel.
* Thus, the most recent Bioconductor "release" where rtracklayer was
successfully distributed on Windows is Bioconductor 3.11.
* Bioconductor 3.11 provides rtracklayer 1.48.0
Clear as mud?
I suspect you're using Suggest: rtracklayer
(https://github.com/timoast/signac/blob/develop/DESCRIPTION) in your
new version. If so, that's good. I also don't think you're doing
anything wrong here. Instead, I think it's one of your other
Bioconductor dependencies under 'Imports:', or possibly under
'Suggests:', that depend on 'rtracklayer'. The fact that error says
"namespace 'rtracklayer' 1.48.0 is being loaded, but >= 1.51.5 is
required.", means that one of those Bioconductor dependencies, or
their dependencies, has an explicit 'rtracklayer (>= 1.51.5)' under
either Depends: or Imports:. My recommendation is that you start
identifying that Bioconductor package, and in what way your 'Signac'
depends on that package. That will help you decide on what to do
PS. This can happen because Bioconductor allows a package to propagate
to a new "release" branch even if it fails on one of the operating
