The package in question is r-irkernel, which is essentially an R package bridging between Jupyter and R. However, it would never be “imported” by the user like other R packages. Instead Jupyter executes R and tells it to run an IPC server written in R. Thus I would consider r-minimal a runtime dependency of r-irkernel. (If r-minimal is not installed then R_LIBS_SITE is not set and R can’t find the package IRkernel whenever Jupyter tries to run R code.) python-ipykernel however does *not* explicitcy depend on python, even though it works exactly the same, whereas jupyter-guile-kernel depends on guile. Any thoughts on this? Thanks, Lars
