lattice is a "recommended" package. Those are contributed packages, not
base packages, so they are optional, but most distributions of R include
them.
Regarding Dirk's "narrower" comment: I think that is really his
decision about the docker container, not a property of R CMD check. R
CMD check needs to be able to succeed if the only packages installed are
the hard dependencies (Depends, Imports, plus base packages), but it
doesn't actually install anything. That's up to you before running it.

Hmm...
I am a little bit confused.
* Is this "narrower" library path for CMD check explained somewhere?
* Isn't lattice one of the default packages (graphics depends on it iirc),
so it should be installed in any case?
Thanks, anyway. So far my tiny test package
https://github.com/otoomet/dummypkg (0.0-1) works, so now I am looking at
vignettes.
Cheers,

Because R CMD check uses a separate 'narrower' library path for checking a
package, you need to install the dependencies of the package you are
checking. So one way to address this is to 'RD CMD INSTALL lattice'
(followed
by whatever else your package needs) in your running Docker session.
