Question

我明确遵循了指令，无法执行任何操作。我对编程几乎一无所知，因此任何反馈或说明将非常有帮助。下载文件并加载漩涡库后，您将需要运行RStudio（或R），然后在控制台中输入以下内容：

install_course_zip(“YOUR_PATH/14_740x_Intro_to_R.zip”,multi=FALSE)

YOUR_PATH是保存在步骤1中下载的zip文件的文件夹路径。通常看起来像这样：

Mac：/Users/johndoe/Desktop

Windows：C:\Users\johndoe\Desktop

我尝试了以下所有操作，供参考，我的文件位置为C:\Users\smari\Desktop，而我进行的尝试如下：

s\smari\AppData\Local\Temp\Rtmps5KyXp\downloaded_packages

| Hi! Type swirl() when you are ready to begin.

我应该能够学习一门有关使用R的课程，然后再输入一些数据进行分析。我需要它做作业。抱歉，没有更多信息，我很困惑。谢谢！

Answer 1

反斜杠（\）是R中的转义字符。要解决此问题，您可以使用\\或使用正斜杠语法对字符本身进行转义（R不在乎您的Windows路径是否用正斜杠声明）。

这意味着

install_course_zip("C:\Users\smari\Desktop_PATH\14_740x_Intro_to_R.zip",multi=FALSE)

应替换为：

install_course_zip("C:/Users/smari/Desktop/14_740x_Intro_to_R.zip",multi=FALSE)

OR

install_course_zip("C:\\Users\\smari\\Desktop\\14_740x_Intro_to_R.zip",multi=FALSE)

尽管遵循指示，仍无法让R加载课程
