当我在针织程序中运行leaflet时,我收到以下错误信息:## error in file(con,"rb"):无法打开连接。然而,当我在常规r中运行这个程序时,没有出现错误消息。以下是我尝试使用的代码(我从获得): index <- inla.stack.index(stack = stk.full, tag = "pred")$data
W: Failed to fetch http://archive.ubuntu.com/ubuntu/dists/quantal/restricted/binary-i386/Packages 404 Not Found [IP: 91.189.88.149 80]
E: Some index files failed to download. They have been ignored, or old ones used instead.
