 Review comment:
   Maybe, another workaround might be possible, but the current one also looks more robust.
   ```
   Setting _R_CHECK_FORCE_SUGGESTS_=false while R_REMOTES_NO_ERRORS_FROM_WARNINGS is unset 
   will also avoid stopping the installation for error messages.
   This is done because a warning is generated during installation 
   when not all Suggested packages are not available.
   ```
