setInternet2无法连接窗口

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，在将win explorer更新到版本8后，这似乎不再起作用。这是在尝试安装e1071以及调用setInternet2选项之后的输出。setInternet2无法连接窗口

任何想法，如果这可以得到纠正？

您可以随时手动下载/安装。你有跟CRAN接触吗？ –

@Misha你确定'setInternet2（TRUE）'是否在从R的任何Web访问之前执行？我在'R-2.13.0 \ etc \ Rprofile.site'的第一行保留了'utils :: setInternet2（TRUE）'。它适用于我与IE8。第二件事：当你在IE中打开版本库目录时，它们是否有问题？ – Marek

与您的网络管理员通话。让他们检查IE8的连接设置是否配置正确。他们也可能阻止某些类型的流量，无论端口是IE8在您的工作场所使用的默认端口。

我想他们会以某种方式阻止它 - 然而奇怪的是，我可以使用IE 8访问相同的文件，无需任何prbs。难道是setInternet2正在使用的.dll文件被查看或阻止了吗？ – Misha
