Question

已下载swirl软件包，以zip方式下载了所有文件，但在运行命令将其解压缩到R时，显示以下信息

install_course_zip("~/Downloads/swirl_courses-master.zip", multi=TRUE, which_course="R Programming")

解压缩时出错（path，list = TRUE）：zip文件＆＃39; C：/Users/sony/Documents/Downloads/swirl_courses-master.zip'不可能是开

Answer 1

第一步（安装R后，当然是启动R）：

> install.packages('swirl')
--- Please select a CRAN mirror for use in this session ---
trying URL ...Your selected CPAN mirror...
Content type 'application/x-gzip' length 98565 bytes (96 KB)
==================================================
downloaded 96 KB

* installing *source* package 'swirl' ...
** package 'swirl' successfully unpacked and MD5 sums checked
** R
** inst
** preparing package for lazy loading
** help
*** installing help indices
** building package indices
** testing if installed package can be loaded
* DONE (swirl)

The downloaded source packages are in
    '/tmp/RtmpUfIWep/downloaded_packages'
Updating HTML index of packages in '.Library'
Making 'packages.html' ... done

请注意，在开始时，当系统要求您选择CPAN镜像时，应显示图形菜单，您必须在其中单击选择。

然后加载库以使用其功能：

library(swirl)

最后，安装课程（注意：在此之前不要启动swirl()）：

> install_from_swirl("R Programming")
  |======================================================================| 100%
| Course installed successfully!

然后，开始课程：

> swirl()

告诉我这些步骤是否有任何（以及哪些步骤）失败。
