Question

我尝试先使用ggplot2安装install.packages("ggplot2")，但在我尝试使用库("ggplot2")打开后，它会向我显示以下错误消息：

library ('ggplot2')

库中的错误（“ggplot2”）：没有名为'ggplot2'的包

这是因为我试图在Mac或RStudio而不是R上运行它吗？我怎样才能安装它？

这些是我正在使用的版本的详细信息：

非常感谢任何帮助！

以下是我尝试将 ggplot 安装为软件包时获得的内容，如果它有帮助...

> install.packages("ggplot2")
Installing package into ‘/Users/crystlewee/Library/R/3.2/library’
(as ‘lib’ is unspecified) also installing the dependency ‘scales’

There are binary versions available but the source versions are later:
  binary source needs_compilation
scales   0.4.0  0.5.0              TRUE
ggplot2  2.1.0  2.2.1             FALSE
Do you want to install from sources the package which needs compilation?

您收到的第一条错误消息是编译scales：

/bin/sh: llvm-g++-4.2: command not found

我对C ++一无所知，但g ++是一个C ++编译器。 ggplot2取决于scales，而scales取决于Rcpp与C ++的接口。确保安装了Rcpp并保持最新。

上面的评论指出您的R版本已过时。如果可能的话，我会更新R.这通常可以解决其中的一些问题。您还要从源代码安装 - 您必须这样做吗？尝试回答“没有”＃39;当提示从源代码和二进制文件安装软件包时。

无法在RStudio上安装和加载ggplot2
