Looks like we're either not checking the version requirement of
dependencies, or something is making 4 > 11... (from my reading of the
code, it is the former, but I could have missed something).
We don't check version requirements of dependencies in install.packages().
That's a minefield related to having multiple versions of a package on a
system and which gets loaded/namespace loaded, so you can easily have the
needed version but pick up a different one.
Depending on whether lazy-loading is in place (and various other issues)
you may or may not need the dependencies to install the package. It's
also a problem that you can update dependencies to incompatible ones, so
the versions available at installation are only part of the story.
I don't see why the message reports .11 not -11, but that may be
related to "package_version" classes.
We should at least document the behaviour.
I am not sure where you think it should be documented and is not.
But for install.packages():
dependencies: logical indicating to also install uninstalled packages
on which these packages depend/suggest/import (and so on
recursively). Not used if 'repos = NULL'. Can also be a
character vector, a subset of 'c("Depends", "Imports",
"Suggests")'.
'uninstalled' seems pretty clear to me.
