In checking my vcdExtra package, the following NOTE newly appeared
(R-Forge, using R version 3.0.1 Patched (2013-08-20 r63635))
Package in Depends field not imported from: ‘gnm’
These packages needs to imported from for the case when
this namespace is loaded but not attached.
In the DESCRIPTION file, I have
Depends: R (>= 2.10), vcd, gnm (>= 1.0.3)
In NAMESPACE:
# we are a vcd extension
import(vcd)
I've read 1.1.1 of R-Exts, but it is not clear to me whether I should
also import gnm or change
the DESCRIPTION file to use
Imports: vcd, gnm (>= 1.0.3)
R-Exts says: The ‘Imports’ field lists packages whose namespaces are
imported from (as specified in the
NAMESPACE file) but which do not need to be attached, but how can I tell
if gnm needs to be attached?
Also, what is the difference between Imports: in DESCRIPTION and
imports() in NAMESPACE?
