Question

过去安装和运行ggplot2没问题，但是突然之间R studio找不到ggplot2软件包。我尝试重新安装该软件包，但是尽管控制台运行了代码并“下载”了该软件包，但library（ggplot2）给了我一个错误：

Error in library(ggplot2) : there is no package called ‘ggplot2’

我已经尝试过：

install.packages("ggplot2",
             repos = c("http://rstudio.org/_packages",
                       "http://cran.rstudio.com"))

我也尝试过：

install.packages("ggplot2", dependencies = TRUE)

我还卸载并重新安装了Rstudio，以admin身份运行，但无济于事

这是控制台在运行命令时显示的内容

install.packages("ggplot2")

控制台输出如下：

Installing package into ‘C:/Users/Keith/Documents/R/win-library/3.3’

  There are binary versions available but the source versions are later:

由于未指定“ lib”，因此无法下载ggplot 2
