Thanks for your answer. I try this trick:

mkdir packages
sudo chmod -R a+w packages
ls -al
drwxrwxrwx��� 2 marcgirondot staff����� 64� 6 d�c 17:20 packages

Now in R

 > require(devtools)
 >
 > install_version("raster", version = "2.5-8", repos 
="http://cran.us.r-project.org",
 ������� lib="/Users/marcgirondot/ Here the full path /packages")

And I get:
Erreur : Failed to install 'unknown package' from URL:
 � (converti depuis l'avis) 'lib = 
"/Users/marcgirondot/Documents/Espace_de_travail_R/packages
"' is not writable

Not sure were I do something wrong.

Thanks if you have an idea.

Marc
