How to link two R packages together
I think all you need to do is add /directory/ to the library search path -- see ?.libPaths Michael

Hi Michael,
Thank you so much for your help!
But my package is not under a directory that can be searched automatically, namely, when load my package, I have to do: library("PKG1",lib.loc=/directory/), in this case, how to write the dependency?
Like 'Depends: PKG1', where can I specify the path?
Thank you so much again!
Yours,
Xuan

Isn't this what package dependencies are for?
See the description of the DESCRIPTION file in Writing R Extensions

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.
