【问题描述】：
在工作中，我通常必须设置 setInternet2(use=TRUE) 选项才能访问 cran 以更新软件包等。但是在他们将 win explorer 更新到版本 8 之后，这似乎不再起作用。这是尝试安装 e1071 后的输出，无论是否调用了 setInternet2 选项。
如果可以补救，有什么想法吗？

【问题讨论】：
-
您可以随时手动下载/安装。你有 CRAN 的浏览器访问权限吗？
-
我最终将 cran 包镜像到我的 USB 上，明天我会带它们去上班。即使在工作中，浏览器也能正常工作。

@Misha 你确定
setInternet2(TRUE)是在R 的任何Web 访问之前执行的吗？我将utils::setInternet2(TRUE)保留在R-2.13.0\etc\Rprofile.site的第一行。它适用于我的 IE8。第二件事：当你在 IE 中打开存储库目录时它们有什么问题吗？ -
@Marek：Yup-setInternet2(TRUE) 在启动时设置，没有任何效果。我直接使用 IE 访问存储库没有任何问题。
