刚刚学习R语言，由于安装的R语言版本比教程的低一版，因此想着更新一下R语言版本。在使用R包的时候，经常会提示另一个版本的警告。不过，这个R的更新还真的太快了，感觉有些招架不住。

更新R
win系统下的更新：
install.packages("installr")
require(installr)
updateR()
IOS用包更新R
install.packages('devtools') #assuming it is not already installed
library(devtools)
install_github('andreacirilloac/updateR')
library(updateR)
updateR(admin_password = 'Admin user password')
官网下载
- go to http://www.r-project.org,

-

自己不知道选那个，最选择了基础安装包，全部安装了。
打开Rstudio默认已经使用最新的安装的R版本，也可以会后自己手动调整。

更新Rstudio

- click on “RStudio ???-XXX”[where ??? is the version and XXX is your operating system]
- it may too slow to download complete, so you should use XUNLEI to download
