R devel - Aug 2013 - cyclic namespace dependency detected when loading ...

Hi R users,


I am developing two packages. Each package uses some functions from the 
other package. Now when I define these dependencies in the NAMESPACE 
file (via importFrom(XXXX,function1,....)), i get this error (when 
building one package):

cyclic namespace dependency detected when loading 'XXXXXX', already 
loading ?YYYYYYY?, ?XXXXXXXXX?

Is there any way to prevent this error? Shouldn't this case be allowed 
in some way? Or can package dependencies only be in one direction?


Thanks
Jannis

Imports only in one direction: Package A has to be installed before 
package B and package B before package A now. The hen and the egg...
