well, I thought that solved it (thanks by the way, that was a silly mistake
), but when I tried to use it :
library("pgirmess")
Erreur : package or namespace load failed for ‘pgirmess’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]):
aucun package nommé ‘rgdal’ n'est trouvé -> this mean he can't find "rgdal"
when I tried to charge rgdal this didn't change anything. An answer ?
