我刚刚创建了一个包 ( RTIO) 和一个包存储库 ( Q:/Integrated Planning/R)，这是一个公司网络驱动器。

我已将包裹放入文件夹：

Q:/Integrated Planning/R/bin/windows/contrib/2.15/RTIO_0.1-2.zip

根据 Dirk 在此SO 中的说明，我运行了以下命令：

> setwd("Q:/Integrated Planning/R/bin/windows/contrib/2.15")
> tools::write_PACKAGES(".", type="win.binary")
> list.files()
[1] "PACKAGES"       "PACKAGES.gz"    "RTIO_0.1-2.zip"
>

使用下面的代码，我已将本地存储库添加到我的存储库列表中（我会让其他用户也这样做）：

options(repos = c(getOption("repos"), RioTintoIronOre = "Q:/Integrated Planning/R"))

现在尝试安装我的包我得到一个错误：

> install.packages("RTIO")
Installing package(s) into ‘C:/Program Files/R/R-2.15.1/library’
(as ‘lib’ is unspecified)
Warning in install.packages :
  unable to access index for repository Q:/Integrated Planning/R/bin/windows/contrib/2.15
Warning in install.packages :
  unable to access index for repository Q:/Integrated Planning/R/bin/windows/contrib/2.15
Warning in install.packages :
  unable to access index for repository Q:/Integrated Planning/R/bin/windows/contrib/2.15
Warning in install.packages :
  package ‘RTIO’ is not available (for R version 2.15.1)

unable to access index for repository告诉我什么？我该如何解决？

我真正想做的是，在 Windows 下并使用 RStudio 作为 IDE，让其他内部 R 用户添加这个包 repo，以便他们能够运行类似的命令install.packages("RTIO")或update.packages() 获取包的新版本（并且可能还有能够使用 IDE 通过 GUI 管理包）。

更新：

感谢agstudy的回答，我更近了一步。这是我得到的输出。

跟进问题：

  1. 为什么在使用时提示我选择存储库setRepositories()？

  2. 当我在不输入数字的情况下点击“输入”并检查getOption("repos")它只显示File://Q:/Integrated Planning/R存储库。这是为什么？

  3. 当我这样做install.packges("RTIO")时，它似乎找到了文件，但给出了警告cannot open compressed file和错误cannot open the connection。注意list.files()上面的输出。知道为什么吗？

为了避免此消息：

Warning in install.packages : cannot open compressed file '//Q:/Integrated Planning/R/bin/windows/contrib/2.15/PACKAGES', probable reason 'No such file or directory'



//在指定 url 时 尝试删除setRepositories

您收到警告unable to access index for repository 是因为install.packages尝试在远程存储库（非本地）中访问您的自定义包。

要解决此问题，您需要将本地存储库添加到您的 R-options repos。您需要将其添加为 url 路径而不是文件路径。类似文件：//

做这样的事情：

      setRepositories(addURLs=c(lRioTintoIronOre = "file://Q:/Integrated Planning/R"))

要检查一切是否正确，以下必须返回 TRUE：

    repos <- contrib.url(getOption('repos'))
    length(grep("^file:", repos)) > 0L
