1.R的安裝

1.1首先添加鏡像源

# Ctrl+Alt+T打開終端
$ sudo gedit /etc/apt/sources.list
# 加入新鏡像源 回車之後會自動跳出一個文本框，然後在相似的地方輸入
deb http://cran.rstudio.com/bin/linux/ubuntu trusty/

載入鏡像源還可以使用以下方法：

deb https://<my.favorite.cran.mirror>/bin/linux/ubuntu xenial/
deb https://<my.favorite.cran.mirror>/bin/linux/ubuntu wily/
deb https://<my.favorite.cran.mirror>/bin/linux/ubuntu trusty/
deb https://<my.favorite.cran.mirror>/bin/linux/ubuntu precise/
or in your /etc/apt/sources.list file, replacing by the actual URL of your favorite CRAN mirror. See 
https://cran.r-project.org/mirrors.html for the list of CRAN mirrors.
