1、在Linux终端窗口打开R:
liyi@liyi:~ > R
2、运用install.packages()函数安装软件包，并且选择镜像，我选择了”中国厦门“作为镜像
R version 3.0.2 (2013-09-25) -- "Frisbee Sailing"
Copyright (C) 2013 The R Foundation for Statistical Computing
Platform: x86_64-pc-linux-gnu (64-bit)

R is a collaborative project with many contributors.
Type 'contributors()' for more information and
'citation()' on how to cite R or R packages in publications.
Type 'demo()' for some demos, 'help()' for on-line help, or
'help.start()' for an HTML browser interface to help.
Type 'q()' to quit R.
> install.packages("randomForest")
3、镜像选择好了以后，函数就在R软件自行下载相关依赖包配置环境：
> install.packages("randomForest")
Installing package into ‘/home/liyi/R/x86_64-pc-linux-gnu-library/3.0’
(as ‘lib’ is unspecified)
4、以上步骤完成以后，只需要最后一步即可：
> library(randomForest)
randomForest 4.6-12
Type rfNews() to see new features/changes/bug fixes.
至此randomForest软件包已经安装好了，用户即可调用软件包的函数来完成自己的数据分析工作了。
