Thanks,
So is it just necessary for suggested packages. So, is it just good practice to make a conditional check? I saw some packages still include it. For example the Seurat package. Under Utils.R (line 349-379) of the SeuratObject-Package (https://cran.r-project.org/src/contrib/Archive/SeuratObject/) you will find the PackageCheck-function which used by the Seurat-Package (https://cran.r-project.org/src/contrib/Archive/Seurat/) to check if packages are alredy installed. You can find examples for DEseq2 under differential_expression.R (starting line 1314 or you cntr+f for packagecheck) in the Seurat.package (https://cran.r-project.org/src/contrib/Archive/Seurat/) or for limma (starting line 2292). ________________________________ Von: Duncan Murdoch <murdoch.dun...@gmail.com> Gesendet: Mittwoch, 3.

Just list it as you would a CRAN package. The CRAN docs talk about "mainstream repositories"; I forget what the definition is of that (maybe repositories listed in `file.path(R.home(), "etc/repositories")`?), but definitely BioConductor is included. > Do I need to make that also conditional?

If any imported package is not available, your package will not load, so errors will happen before you ever get to running examples. > that the Bioconductor dependencies dont cause a rejection from CRAN? Just make sure they exist on BioC and your code works with them.
