MySQL5.5的RMySQL安装问题

Question

我对R很陌生，但我在编程方面有一些经验。我尝试在装有MySQL Workbench 5.2的Windows7上安装RMySQL，但不断收到相同的错误。我已经检查了不同的程序，但仍然卡住了：

MySQL已经启动并运行，我已经移动了libmysql.lib和libmysql.dll，但我一直收到以下错误。我想我看不出问题到底是什么。你有什么建议吗？

这都是使用R版本2.13.2实现的。

我最近在32位WinXP上安装了RMySQL，也遇到了一些问题。我在下面的link中记录了我遇到的问题和解决方案

几天前，我还与包的维护者进行了跟进。我还没有收到回复。希望我们能更好地记录这个过程。您的问题似乎可以通过发出r语句来解决：

Sys.setenv(“MYSQL_HOME”=”C:/PROGRA~1/MySQL/MYSQLS~1.5″)

在安装RMySQL之前。
