如何使用自定义目录位置来安装R软件包 [英] How to use a customized directory location for installing R packages

问题描述

我在Windows 8.1上运行带有R 3.0.1的Rstudio 0.97.我通过Rstudio安装了很多软件包，它们都转到"\ R \ R-3.0.1 \ library".现在，我安装了R 3.1.0，并将Rstudio设置为使用新版本的R.但是随后，我发现Rstudio都无法访问这些软件包.

I am running Rstudio 0.97 with R 3.0.1 on Windows 8.1. I installed a lot of packages through Rstudio and they all went to "\R\R-3.0.1\library". Now I installed R 3.1.0 and set Rstudio to use the new version of R. But then I found the packages are all inaccessible from Rstudio.

如何将软件包制作在共享文件夹中，以便PC上不同版本的R都可以使用它们?

How to make the packages in a shared folder so that the different versions of R on my PC can all use them?

我试图使用.libPaths("XXXX package sharefolder")设置一个共享文件夹来存储和安装新软件包，它在会话中有效，但是当我重新启动Rstudio时，路径会重置.没用.

I tried to use .libPaths("XXXX package sharefolder") to set a sharefolder to storing and installing new packages, it works in a session but when I restart Rstudio, the path is reset. Didn't work.

推荐答案

首先，如果需要，请mkdir ~/whatever-you-want.

第二，将R_LIBS_USER="~/whatever-you-want"添加到'~/.Renviron'.

因此，如果您要重复使用\R\R-3.0.1\library，请在'~/.Renviron'中添加R_LIBS_USER="\R\R-3.0.1\library".如果使用Windows，请将.Renviron放在C:\Users\<user-name>\中.

So, if you want to reuse \R\R-3.0.1\library as you mentioned, add R_LIBS_USER="\R\R-3.0.1\library" to your '~/.Renviron'. If you are using Windows, put the .Renviron in C:\Users\<user-name>\.
