Dear All,
I understand the R CMD checks with only the base package attached,
everything else (including the other packages bundled with the base R)
should be imported and most importantly declared in the Imports field from
the DESCRIPTION file.
However, I do use functions from other packages than base (utils,
grDevices, stats, graphics), for which it is sufficient to declare
importFrom() in the NAMESPACE file.
For instance, it is not required to specify utils in the Imports: field
from DESCRIPTION, when using importFrom("utils", "packageDescription") in
NAMESPACE.
The opposite happens for importFrom("methods", "is"), which ends up in the
error: Namespace dependency not required: ‘methods’
Is there a special reason for which package methods is treated differently
from all other packages bundled with the base R?
Thank you,
Adrian
