脱机安装R软件包 [英] Offline Installation of R packages

问题描述

我的研究所使用代理服务器，没有人能够以通常的方式安装软件包. (即从CRAN下载二进制文件，然后选择Mirro并进行安装等).

My institute uses proxy server, and no one is able to install packages in a usual way. (i.e downloading binary file from CRAN and then choosing Mirro and the installing etc etc).

如果我在学院以外使用互联网，则可以安装软件包.

I am able to install packages if I use internet outside of my institute.

因此，我正在寻找一种离线安装软件包的方法.请提供详细的解决方案，我刚刚开始使用R.

So, I am looking for an offline way to install packages. Please provide a detailed solution, I have just started using R.

推荐答案

这是我的解决方法.可能对您也有帮助.

This is my work around. Might be helpful for you too.

想法:通过互联网下载具有相关性的软件包，然后离线安装软件包.

Idea: Download packages with their dependencies through internet and install packages offline.

# Set Mirror to download packages    
options(repos=structure(c(CRAN="http://cran.ma.imperial.ac.uk/")))

 # Set Working Directory   
    setwd(file.path(
        "D:"
      , "User"
      , "DownloadingPackagesWithDependencies"
      )
      )


getPackages <- function(packs){
  packages <- unlist(
      tools::package_dependencies(
          packs
        , available.packages()
        , which=c("Depends", "Imports")
        , recursive=TRUE
        )
      )
    packages <- union(packs, packages)
    packages
  }

# Specify Packages to Download with their dependencies also   
Packages <- getPackages(
                c(
                  "ggplot2"
                  )
                )


download.packages(
    pkgs=Packages
  , destdir=getwd()
  , type="source")

# Install packages from local drive
    install.packages(
        pkgs="ggplot2_0.9.3.1.tar.gz"
      , repos = NULL
      , type="source"
       )
