问题描述
我不知道这是否已经在堆栈溢出这里已经被回答了。我的Unix机器上安装了Emacs-ESS，当我启动emacs时，R的特定版本被加载。
我现在有一些新的R包，我想在安装到默认R环境之前进行测试。因此，我在本地目录中安装了较新版本的R，并将我的新软件包安装在那里。现在，如果我想把这个更新的R版本，我安装在本地目录，从emacs，我应该怎么做？我想要能够调用默认的R版本或本地安装的R版本。
I am not sure if this has already been answered here on stack-overflow. I had Emacs-ESS installed on my Unix machine and when ever I start up emacs, particular version of R gets loaded. I now have some new R packages that I wanted to test before installing into default R environment. Hence I installed newer version of R in a local directory and have my new packages installed there. Now if I want to call this newer R version that I installed in a local directory, from emacs, how exactly should I be doing it? I want to be able to call either the default R version or the locally installed R-version.

ESS可以启动其他版本的R，前提是它知道您所在系统的位置。以下粘贴在中的相关部分：
ESS can start other versions of R, provided that it knows where on your system they are located. Pasted below is the relevant section from the ESS manual:

R-1.8.1，则可以使用Mx R-1.8启动

ESS将找到R开始
R-1或R-2的版本。如果您的R
的版本被称为其他名称，请考虑
使用符号链接重命名它们，或
更改变量ess-r-versions。到

R on Unix systems: If you have "R-1.8.1" on your exec-path, it can be started using M-x R-1.8.1. By default, ESS will find versions of R beginning "R-1" or "R-2". If your versions of R are called other names, consider renaming them with a symbolic link or change the variable ess-r-versions. To see which functions have been created for starting different versions of R, type M-x R- and then hit [Tab]. These other versions of R can also be started from the "ESS->Start Process->Other" menu.
