【R语言】R语言版本和Rstudio的更新

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

1. go to http://www.r-project.org,
2. click on ‘CRAN’2,
3. then choose the CRAN site that you like. I like lzu: https://mirror.lzu.edu.cn/CRAN/.
4. click on ‘Download R for XXX’ [where XXX is your operating system]
5. follow the installation procedure for your operating system
6. restart RStudio

7. rejoice
   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。
