Thanks,
I thought about changing it to "Imports", but will it cause any issues when
CRAN runs checks on my package and limma isn´t available on CRAN?
No, BioC is a mainstream repository.
Best,
Uwe Ligges

Strictly speaking, no. Once you list limma under Suggests, it's
possible and proper to install your package using
BiocManager::install('YOUR_PACKAGE', dependencies = TRUE) and have
limma installed too, as Martin Morgan said above in the thread.
Some recommend adding biocViews:
This field is required on Bioconductor, not CRAN:
https://contributions.bioconductor.org/description.html?q=biocViews#description-biocviews
some recommend adding Remotes: bioc::limma
Not a standard R/CRAN field, only used by the remotes package:
https://remotes.r-lib.org/articles/dependencies.html
Others add Biocmanager to the suggests file
I suppose it could help a user who doesn't initially know to use
BiocManager in order to install your package, and could also be used to
install limma on behalf of your users (with their permission!), but
it's additional work, may be hard to get right (see the CRAN policy
about installing packages and touching user files), and is not required
at all.
What should I add to my Description File to make sure that limma gets
installed from Bioconductor when needed?
See Martin Morgan's e-mail above in the thread. In short, tell your
users to install your package using BiocManager::install(...,
dependencies = TRUE) if they want limma to work. They are still free to
install.packages() if they don't want limma or can set things up
themselves.
Move limma to Imports (better) or Depends (may be worse)
if you want limma to be always available, at the cost of always
requiring Bioconductor to be set up to have your package installed.
There are other ways besides BiocManager::install(), but they all
depend on the user having set up Bioconductor repos in their R session
somehow, be it BiocManager::repositories() or setRepositories().
