Isn't this what package dependencies are for?
No. It's what package imports are for (preferably). As always, the OP should RTFM -- in this case the one to which you refer on the next line, especially the NAMESPACES section.
But note that the original question included, "when I load one package
using 'library("PKG1")', PKG2 can be loaded at the same." which
imports does not exactly do. They become available to the package, but
not to the user, so if you really need both packages loaded to the
search path, then you need a dependency, not imports.
Cheers,
Josh

Hi,
I have built two R packages. One of them (PKG1) needs to use the functions
of the other package (PKG2).
So I need to link these two packages together, so that the functions of PKG2
can be available to PKG1. And when I load one package using
'library("PKG1")', PKG2 can be loaded at the same.
Any ideas welcome.
