На работе мне обычно приходится устанавливать опцию setInternet2(use=TRUE), чтобы получить доступ к крану для обновления пакетов и т. Д. Однако после того, как они обновили win explorer до версии 8, похоже, это больше не работает.Это вывод после попытки установить e1071 как с опцией setInternet2, так и без нее.
Есть идеи, если это можно исправить?
