我是R的新手，我只是想尝试一些教程。

当我尝试安装ggp​​lot2时，出现此错误。

Error in library(ggplot2) : There is no package called 'ggplot2'

我在R和RStudio中尝试了这些。

install.packages("ggplot2", dep=T)

install.packages('ggplot2', repos='http://cran.us.r-project.org')

remove.packages("ggplot2")

但我得到了错误

(Error in remove.packages : there is no package called 'ggplot2')

这就是我从install.packages（“ ggplot2”）获得的内容
