r - install.packages 错误 : Troubleshooting local repo usage

Question

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。

我已将我的包裹放入文件夹中:
Q:/Integrated Planning/R/bin/windows/contrib/2.15/RTIO_0.1-2.zip
按照 Dirk 在 this 中的说明所以，我已经运行了以下命令:

> 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(我将让其他用户也这样做):

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

现在尝试安装我的软件包时出现错误:

> 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)

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

我真正想做的是，在 Windows 和 RStudio 作为 IDE 的情况下，让其他内部 R 用户添加这个包存储库，以便他们能够运行像 install.packages("RTIO") 这样的命令。或 update.packages()获取包的新版本(并且大概还能够使用 IDE 通过 GUI 管理包)。

更新:

多亏了 agstudy 的回答，我又近了一步。这是我得到的输出。

> getOption("repos")

Error in install.packages : cannot open the connection

跟进问题:

为什么在使用setRepositories()时提示选择仓库?

当我在没有输入数字的情况下点击“回车”时，检查 getOption("repos")它只显示 File://Q:/Integrated Planning/R存储库。这是为什么？

当我这样做时 install.packges("RTIO")它似乎找到了该文件，但给出了警告 cannot open compressed file和一个错误 cannot open the connection .注意 list.files() 的输出以上。知道为什么吗？

Answer 1

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'

试试这个删除 //在 setRepositories 中指定 url 时

> setwd("Q:/Integrated Planning/R/bin/windows/contrib/2.15")
> tools::write_PACKAGES(".", type="win.binary")
> setRepositories(addURLs=c(RioTintoIronOre = "file:Q:/Integrated Planning/R"))
> install.packages("RTIO")
