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

ks is listed in the Imports: line in the DESCRIPTION file of the package
in question, not in the Depends: line.

	@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.

Again, this depends should read Imports.

Sorry if this created confusion.

Cheers,
