我的计算机上正在运行哪个版本的R? [英] Which version of R is running in my computer?

问题描述

我的计算机上有两个R目录:
一个是/home/R-2.15.2，另一个是/home/R-2.15.1，
当我输入R时，我可以启动R，现在我想知道哪个R正在运行:2.15.1或2.15.2?

There are two R directories on my computer:
one is /home/R-2.15.2,the other is /home/R-2.15.1,
when I input R , I can start R, now I want to know which R is running: 2.15.1 or 2.15.2?

推荐答案

运行R --version第一行中包含有关版本的信息.

Run R --version there's info about version on the first line.

如果您问这个问题，那么我敢打赌R不在任何这些目录中运行.检查$ PATH env变量以获取查找二进制文件的位置和顺序的信息.

If you ask this question then I bet that R is not running from any of these directories. Check $PATH env variable to get information where binaries are looked for and in which order.

使用type shell命令来查找给定命令的二进制存储位置，所有路径的-a，散列路径的-f(基本上:最近使用).

Edit 2: Use type shell command to find where binary for given command is stored, -a for all paths, -f for the hashed one (basically: most recently used).
