Question

我尝试安装包raster，因为classInt未安装，因此我退出状态为非零。

我最近更新并升级了Ubuntu上的所有R软件包和R-core（到3.1）。

现在，如果我尝试从CRAN存储库安装软件包classInt，或者甚至手动执行（下载tar.gz并设置repos），我会收到以下错误代码：

package ‘classInt’ is not available (for R version 3.1.0)

关于如何调试这个的想法？

整个错误输出完成帖子：

好的，事实证明问题在于.Rprofile的使用。 .Rprofile是一个在每个RSession开始时自动执行的小脚本。它应该增强您的工作流程，因为您可以在那里调用一些常用的库，而不是每次都在脚本中调用它们。

当我仍在使用R 2.15时，我使用file.edit("/home/user/R/.Rprofile")编辑了此个人资料，并使用classInt拨打了library("classInt"). 现在，在升级到R 3.1之后，创建了包的新库路径，并且需要再次重新安装大多数其他包。那时我没有重新安装classInt。

现在R做的是每次classInt在启动时调用，因为没有安装软件包并且生成了错误消息Error in library("classInt") : there is no package called 'classInt'。我在启动时总是忽略这个消息，因为它不会影响我。

现在从library("classInt")删除行.Rprofile后，我可以安装raster包而不会显示任何错误消息，我也可以重新安装classInt或任何其他所需的包。所以我猜想在会话启动时调用classInt失败后，R无法安装任何软件包。

包'classInt'不可用（对于R版本3.1.0）
