This seems to be the same problem discovered here and elsewhere. {renv} current dev version has been fixed to not include "R" as a R package dependency, but I suspect a better solution would be to follow the same solution as in RMI-PACTA/workflow.transition.monitor#231, which was to drop using {renv} at all and instead use pak::local_deps() or pak::local_install_deps().

Agree that having a DESCRIPTION file is a more elegant solution.
