Question

我正在尝试安装“RPostgreSQL”软件包（使用R 2.13.1，Mac OS X Snow Leopard）。

当我运行install.packages("RPostgreSQL")时，我收到此错误：

In getDependencies(pkgs, dependencies, available, lib) :
  package ‘RPostgreSQL’ is not available (for R version 2.13.1)

所以我尝试从源代码下载并运行r CMD INSTALL RPostgreSQL_0.1-7.tar.gz，它似乎安装得很好，但是当我调用library(RPostgreSQL)时，我收到此错误：

`Error: package 'RPostgreSQL' is not installed for 'arch=i386'`

所以我随机尝试重新运行r CMD INSTALL RPostgreSQL_0.1-7.tar.gz，这似乎再次正常安装，但是当我拨打library(RPostgreSQL)时，我收到的错误略有不同：

'RPostgreSQL' is not a valid installed package

知道什么是错的吗？是不是最新版本的R不支持包，所以我应该降级我的R版本（我想，通过卸载我当前的版本并找到一个较旧版本？）如果我想使用它？

该软件包未在CRAN上构建。请参阅CRAN page for details，表示MacOS X二进制文件不可用。包无法安装。这是安装日志：

您应该联系软件包维护者以获取更多信息。

RPostgreSQL repo on Google Code有installing RPostgreSQL on Mac OS X的明确文档，我建议你从那里开始。

Neil也会尝试保持这些最新状态，所以无论出于何种原因，如果这对你失败，你总是可以来Google Groups mailing list。

包'RPostgreSQL'不可用（对于R版本2.13.1）？
