【R語言】R語言版本和Rstudio的更新

剛剛學習R語言，由於安裝的R語言版本比教程的低一版，因此想着更新一下R語言版本。在使用R包的時候，經常會提示另一個版本的警告。不過，這個R的更新還真的太快了，感覺有些招架不住。

更新R

win系統下的更新：

install.packages("installr")
require(installr)

IOS用包更新R

library(devtools)
install_github('andreacirilloac/updateR')
library(updateR)
updateR(admin_password = 'Admin user password')

   自己不知道選那個，最選擇了基礎安裝包，全部安裝了。
   打開Rstudio默認已經使用最新的安裝的R版本，也可以會後自己手動調整。
