G'day all, looking at http://cran.at.r-project.org/web/checks/check_results_Sleuth2.html I noticed that r-prerel-* and r-devel-* issue notes. Apparently, now examples are more thoroughly checked by R CMD check and the note pointed out that a package used in the examples was not declared. This was easily fixed by adding 'Suggests: lattice' to the DESCRIPTION file (now this change has to migrate through R-forge to CRAN).
But then I noticed that for another package I have on R-forge a similar note is issued: https://r-forge.r-project.org/R/?group_id=630&log=check_x86_64_linux&pkg=DeconWK&flavor=devel O.k., R-forge is using R-devel, so I installed R 2.12.0 RC (2010-10-10 r53273) on my machine to check, same note is issued. The note issued by R CMD check says: * checking for unstated dependencies in examples ... NOTE 'library' or 'require' call not declared from: ks which is a bit surprising. There are three .Rd files that have a library(ks) in them and ks is listed in the Imports: of the description file. This seems to be completely in line with the documentation in "Writing R extensions": @item Packages whose name space only is needed to load the package using @code{library(@var{pkgname})} must be listed in the @samp{Imports} field and not in the @samp{Depends} field. that's why ks is listed in depends @item All packages that are needed to successfully run @code{R CMD check} on the package must be listed in one of @samp{Depends} or @samp{Suggests} or @samp{Imports}. [...] which seems to be adhered to, since ks is in the depends. But upon digging into .check_packages_used_in_examples in QC.R in package tools, I have the impression that packages loaded in examples via library() or require() are only checked against packages listed in Suggests, Enhances and Depends, the package's own name and the standard packages, but not against those listed in Imports. Thus, I believe there is some disconnect between documentation and behaviour at the moment. In this particular case, possible solutions would be to list ks in both, Imports and Suggests, or, to have only one entry, to move it to Depends. But I believe the cleaner solution would be that .check_packages_used_in_examples includes the packages listed in Imports when checking whether all packages used in library() or require() commands in examples are declared.
