我正在与在 Windows 7 64 位的 R2.13.0 上安装 RMysql 作斗争。我的mysql 5.5、64bit的版本。以下是导致我出错的步骤：

  1. 安装 RTools
  2. 通过调用设置代理：FAQ@CRANsetInternet2(TRUE)之后
  3. 设置 MYSQL_HOME:Sys.setenv("MYSQL_HOME"="C:\\Program Files\\MySQL\\MySQL Server 5.5\\")在这个帖子之后
  4. 在 R 控制台中调用：install.packages("RMySQL", type="source")

4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)

替代 4 只是安装包：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)

我确信我没有连接问题，因为我可以调用 R update。谁能帮我找出如何从 R 访问 mysql db？

附言。这是 sessionInfo() 的输出

R version 2.13.0 (2011-04-13)

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。在我看来应该是

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

或类似的东西。您可以通过尝试打开您在浏览器中发布的 URL 进行检查。
