安装ggplot2时出错

Question

我试图在ggplot2上运行一个简单的代码，得到了以下错误：

source("u1.txt")
Error in library(ggplot2) : there is no package called ‘ggplot2’


Error : package ‘foreign’ was built before R 3.0.0: please re-install it

Answer 1

今天晚上运行ggplot时也发生了同样的错误，本质上您需要尝试安装所有失败的依赖项。对我来说，这是“尺度”，然后是“芒塞尔”，最后是(实际的问题)“颜色空间”，自从我升级到3.1.1之后就没有更新过。在您的示例中，您似乎希望先尝试安装"foreign“，然后再试一次ggplot2。继续手动加载该错误的依赖项，直到找到真正的问题为止。

Answer 2

您可以指定install.packages()调用还安装所有依赖的包：

if(!require(ggplot2)) install.packages('dplyr',dependencies = TRUE)

上面的代码首先检查是否加载了ggplot2包，如果没有，则尝试加载apckage。如果无法加载包，则尝试安装包和所有包的依赖项。

Answer 3

安装了RTools之后，我就可以使用它了：

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

汇编了一些软件包..。

确保您的路径被更新为正确指向RTools，即包括

c:\Rtools\bin;c:\Rtools\gcc-4.6.3\bin

在前面。

我正在使用Rtools32.exe
