[R] "Error in package manager"

[laure gallien]

Hi all,

I am quite new to R, and I guess i made a mistake with
it... 
Now, when i want to open the package manager i got
this :

"Erreur dans package.manager(is.loaded, pkgs,
pkgs.desc, pkgs.url) : 
  invalid arguments (length mismatch)
De plus : Warning message:
In .find.package(pkgs) : aucun package nommé
'file56e509fe' n'est trouvé"

Well, it is in french... saying that it didn't find
the package call "ile56e509fe".

Can you help me ??
I already tried to download a new R version (for my
MacOS X) and the last R GUI...And the problem is still
there...


Thanks a lot,

Laure
