The prototypical situation is this

> f<-function(a=a)a
> f(2)
[1] 2
> f()
Error in f() : recursive default argument reference

The default for argument a ends up needing the value of a. This can
also happens more indirectly when multiple arguments refer to
eachother. 

BTW: Is that error message proper French? Should it not be

référence récursive d'argument par défaut 

or so.
