XLConnect是“允许从R内读取，写入和操作Microsoft Excel文件的软件包”。
在Windows和Linux上安装非常简单。简单地告诉R install.packages("XLConnect")，你已经完成了。在OS X上，您需要使用install.packages("XLConnect", type="source")，安装说明如下。
在OS 10.8.2下尝试此操作，R输出许多错误消息。我将它们发布在此处，因此Google可以向此Q和A发送类似问题的人。要解决此问题，请向下滚动。
R输出：
> install.packages("XLConnect", type = "source")

Mac OSX上的安装比installation instructions建议的要复杂一点。该软件包的开发人员Mirai Solutions的Martin Studer帮我解决了我的困难，我想在这里发布这个程序，以帮助其他用户遇到同样的问题。
