Thanks for your answer. That's quite weird, since the ftp works. Maybe connected to openbsd version? I am on 5.6 release.
This is not a drama though, it will motivate me to use as less additionnal packages as possible. Damien Thiriet
I just tested install.packages("maptools", repos = "http://r.meteo.uni.wroc.pl") and it worked fine. Does $ ftp http://r.meteo.uni.wroc.pl/src/contrib/PACKAGES work?
