Providing a default argument list=character() seems to fix
package.skeleton for this example. Should be in the next version of R
2.7 beta.
Regarding your other example. This looks more like a real error in your
code.
Error in le > 0 : comparaison (6) possible seulement pour les types
liste et atomique
De plus : Warning message:
In is.na(le) :
is.na() appliqué à un objet de type 'S4' qui n'est ni une liste, ni un vecteur
These sound like legitimate error messages. However, try this example
with the corrected package.skeleton() as well.
