我在 Windows 7 64 位上的 R2.13.0 上安装 RMysql 时遇到了麻烦。我的mysql版本是5.5，64位。以下是导致我出错的步骤:

1. 安装 RTools
2. 通过调用设置代理:setInternet2(TRUE)之后FAQ@CRAN
3. 设置 MYSQL_HOME: Sys.setenv("MYSQL_HOME"="C:\\Program Files\\MySQL\\MySQL Server 5.5\\")之后this post on SO
4. 调用 R 控制台:install.packages("RMySQL", type="source")

4之后，我收到以下错误:

Installing package(s) into ‘C:/Users/Foo/Documents/R/win-library/2.13’
(as ‘lib’ is unspecified)
Warning: unable to access index for repository http://artfiles.org/cran/src/contrib
Warning message:
In getDependencies(pkgs, dependencies, available, lib) :
  package ‘RMySQL’ is not available (for R version 2.13.0)

4 的替代方案只是安装软件包:install.packages("RMySQL") 。在这种情况下我得到:

Installing package(s) into ‘C:/Users/foo/Documents/R/win-library/2.13’
(as ‘lib’ is unspecified)
Warning: unable to access index for repository http://artfiles.org/cran/bin/windows/contrib/2.13
Warning message:
In getDependencies(pkgs, dependencies, available, lib) :
  package ‘RMySQL’ is not available (for R version 2.13.0)

我确信我的连接没有问题，因为我可以调用 R update。有人可以帮我找出如何从 R 访问 mysql 数据库吗？

ps。这是 sessionInfo() 的输出

R version 2.13.0 (2011-04-13)
Platform: i386-pc-mingw32/i386 (32-bit)

locale:
[1] LC_COLLATE=German_Germany.1252  LC_CTYPE=German_Germany.1252   
[3] LC_MONETARY=German_Germany.1252 LC_NUMERIC=C                   
[5] LC_TIME=German_Germany.1252    

attached base packages:

更新:我在没有代理的情况下直接连接到互联网，现在我得到了:

> install.packages("RMySQL", type="source")

您应该仔细检查您正在使用的存储库。我觉得应该是这样

install.packages("RMySQL", repos='http://artfiles.org/cran.r-project.org/')

或者类似的东西。您可以通过尝试打开您在浏览器中发布的 URL 来进行检查。
