尽管按照说明操作，但仍无法让 R 加载类

Question

>我明确遵循了说明，无法运行任何内容。我对编程几乎一无所知，所以任何反馈或说明都会非常有帮助。下载文件并加载 swirl 库后，您需要运行 RStudio(或 R(，并且 在控制台中输入以下内容：

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

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

 苹果：/Users/johndoe/Desktop

 窗口：C:UsersjohndoeDesktop

我已经尝试了以下所有方法，作为参考，我的文件位置是C:UserssmariDesktop，我所做的尝试如下：

ssmariAppDataLocalTempRtmps5KyXpdownloaded_packages

我应该能够运行一个关于使用 R 的课程，然后输入一些数据进行分析。我需要它做作业。很抱歉没有更多信息 - 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\或使用正斜杠语法转义字符本身(R 不关心您的窗口路径是否用正斜杠声明(。

这意味着

install_course_zip("C:UserssmariDesktop_PATH14_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)

或

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