Question

当我在我的Windows机器上启动R时，我会在日志下面。为什么我会在下面收到2个错误？我怎么能调试它们？问题与包Arules和Matrix有关吗？为什么我只为这两个包收到此错误？我还在同一个地方安装了其他的包......

当它说“以下对象被'package：base'掩盖时，它是什么意思： “？

这可能与R的安装位置中的空格有关，不建议参见：

Answer 2

你刚刚重新安装R？当它试图重新加载旧的.RData文件并且正在寻找不再存在的东西时，它似乎在抱怨。它也可能是文件名中的空格问题。我通常会覆盖默认路径并在路径中没有空格的目录中安装R（通常是C：\ Apps \ R \ R-3.1.0，其中Rtools在C：\ Apps \ R \ Rtools中）。这使得批处理脚本不那么麻烦......
