Thanks for the quick & helpful reply! The following seems to fix my problem:
1) As advised, set
Imports: Rcpp
LinkingTo: Rcpp, RcppArmadillo
[my original version had imported RcppArmadillo in addition]
2) Delete the following line from the NAMESPACE file generated by
RcppArmadillo.package.skeleton():
import(RcppArmadillo)
Now "R CMD check --as-cran" goes through without the note (or any other
notes/warnings), and the package seems to work as intendend.
Thanks again & best regards,
Fabian

You probably have
Depends: Rcpp, RcppArmadillo
or
Imports: Rcpp, RcppArmadillo
when you only need
Imports: Rcpp
LinkingTo: Rcpp, RcppArmadillo
See eg the RcppMLPACK package as a recent example, and edit your DESCRIPTION
accordingly.

The RcppArmadillo.package.skeleton() function may need updating then with
respect to Imports -- looks like it was last touched in May.
I'll check that over the next few days.

| MWE
| --------
| As a MWE (which I think/hope reproduces the issues that are relevant
| here), consider the following toy example:
|
| - Call RcppArmadillo.package.skeleton("xyz"), producing the new package
| folder "xyz"
| - Add formally correct documentation files to folder "xyz/man" (that is,
| add entries for all exported functions and the package itself; delete
| between-text comments produced by skeleton function).
| - Add license information to file "xyz/DESCRIPTION": "License: GPL (>= 2)"
|
| Running "R CMD check xyz" goes through without any notes or warnings.
| Running "R CMD check --as-cran xyz" yields the exact same note as above
| (plus the "new submission" note), but no other notes/warnings. [I did
| not post the fake docu files for package "xyz" to avoid spamming - if
| anyone wants them, pls let me know]
