错误 setwd() “无法更改工作目录”

Question

I get "cannot change working directory" error when I try to set up my working directory:尝试设置工作目录时出现“无法更改工作目录”错误：

    setwd("C:\Users\alimo\Desktop\DataVisualizationwithggplot2.R")
*Error: '\U' used without hex digits in character string starting ""C:\U"*

then I did it然后我做到了

options(PACKAGE_MAINFOLDER="C:/Users/...")

then I replaced all " \ " to "/" but I got it this time:然后我将所有“\”替换为“/”，但这次我明白了：

cannot change working directory

Please help me.请帮我。

Yes, writing a path to a file or directory can sometimes be a bit painful, especially when you move across different platforms!是的，写入文件或目录的路径有时会有点痛苦，尤其是当您跨不同平台移动时！

setwd() sets the working directory, so it means you need to specify a directory, not a file. setwd()设置工作目录，所以这意味着你需要指定一个目录，而不是一个文件。

And whenever I'm not sure about the single/double (back)slashes, I like to use file.path() from base R, which adds a correct delimiter in a platform-independent way:每当我不确定单/双（反）斜杠时，我喜欢使用基础 R 中的file.path() ，它以独立于平台的方式添加正确的分隔符：

file.path("~", "myfolder", "myfile.R")

So for your case:所以对于你的情况：

setwd(file.path("C:", "Users", "alimo", "Desktop"))
