库中的错误(Ggplot2)：没有名为“ggplot2”的包

Question

我是R的新手，我只是试着通过一些教程。

当我尝试安装ggplot2时，会发现这个错误。

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

我在R和RStudio上试过这些。

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

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

remove.packages("ggplot2")

但我明白错误

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

这就是我从install.packages("ggplot2")得到的信息。

> install.packages("ggplot2")

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。

这些代码使用R3.4.2运行

Answer 1

在提出这一问题时，我建议：

• 试着一次又一次地关掉它
• 如果可能，将R更新为最后版本
• 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 2

步骤

1. 使用工具
2. 安装软件包
3. 在包中，文本框类型为ggplot2
4. 选中“安装依赖项”复选框

Answer 3

尝试从命令提示符直接启动R客户机，然后发出指令: lib="C:/Users/YourUser/Documents/R/win-library/3.3") (“ggplot2”，ggplot2)
