Question

我是R的新手，而我只是想通过一些教程。

当我尝试安装ggplot2时，我收到此错误。

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

我在R和RStudio中试过这些。

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

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

remove.packages("ggplot2")

但我收到了错误

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

这是我从install.packages获得的内容（＆＃34; ggplot2＆＃34;）

> install.packages("ggplot2")
Installing package into ‘.../R/win-library/3.4’

Warning in install.packages :

Warning in install.packages :

The downloaded binary packages are in
    C:...\AppData\Local\temp\RtmpqaGNpr\downloaded_packages

我手动删除了所有ggplot2文件，然后再次尝试安装。这是我的结果。

Answer 1

步骤

转到工具
安装包
在包文本框中键入ggplot2
选中复选框安装依赖项

Answer 2

遇到这个问题时，我建议：

尝试将其关闭再打开
如果可能，将R更新为最新版本
手动删除与相关包相关的所有文件夹，然后重试安装
更改默认库位置：How do you change library location in R?

Answer 3

您需要更新R版本并执行此操作，但是您需要再次安装所有软件包：

工具>全局选项> R版本（更改）>选择“使用计算机的默认R ...”

Answer 4

尝试直接从命令提示符启动R客户端，然后发出以下指令： install.packages（“ ggplot2”，lib =“ C：/Users/YourUser/Documents/R/win-library/3.3”）

R 3.4.2库中的错误（ggplot2）：没有名为＆＃39; ggplot2＆＃39;
