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.
