旋流加載問題

Question

下載了swirl包，並以zip格式下載了所有文件，但運行命令以在R中解壓縮時，它顯示以下消息

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

解壓縮錯誤（路徑，列表= TRUE）：zip文件'C：/Users/sony/Documents/Downloads/swirl_courses-master.zip'無法打開

Answer 1

第一步（安裝R之后，當然要啟動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

請注意，一開始，當要求您選擇CPAN鏡像時，將出現一個圖形菜單，您必須在其中單擊選擇。

然后加載庫以使用其功能：

library(swirl)

最后，安裝該課程（注意：在此之前不要啟動swirl() ）：

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

然后，開始課程：

> swirl()

告訴我這些步驟是否失敗。
