[R]package dependence

[Christian Hoffmann]

Hi,

I want to create several packages, with package Aa depending on functions
in package A. My directories with .r and .Rd are organized as follows

./A/man/*.Rd
./A/R/*.r
./Aa/man/*.Rd
./Aa/R/*.r

Afre creatin package A with 

R CMD check A 
R CMD INSTALL --library=lib A

I then have
./lib/A/help  etc

If I try to do

R CMD check Aa 
R CMD INSTALL --library=lib Aa

I am getting

* checking examples ... ERROR
and in ./Aa.Rcheck/Aa-Ex.Rout

there is the error signalled

	couldn't find function "function.from.A"
Execution halted

Since I rather want to keep the packages separate, how can I deal with
dependences among packages?


Thanks for help.
