RDataEngineer-06-02.R 和 RVisualization-04-HW.R 無法結束 #345

Open crikyre opened 7 years ago

crikyre commented 7 years ago

如題，我用網頁上的解答也無法解決， 是不是有版本的問題呢？ 謝謝!

錯誤資訊如下： RDataEngineer-06-02.R ： Error : nrow(answer02.1) == 116774 is not TRUE

RVisualization-04-HW.R： Error in file(con, "r") : cannot open the connection In addition: Warning message: In file(con, "r") : cannot open file 'NA': No such file or directory

感謝你的回報。不好意思，因為家中有新成員，所以目前我沒辦法太頻繁的回覆問題。

RDataEngineer-06-02.R

可能和nycflights這個套件的版本有關，請問你目前電腦上的版本是？ 參考看看 https://github.com/wush978/DataScienceAndR/issues/319 是不是已經修復了

RVisualization-04-HW.R 這個你是第一次回報的，所以我不清楚原因耶。 還是先請你重新安裝一次看看，以及檢查使用者名稱是不是有中文（限windows使用者）

crikyre commented 7 years ago

版本原來不是最新的， 現在已經都是最新的，R 是3.3.2 R studio是1.0.44 雖然有照解答安裝 check_then_install("nycflights13", "0.1")

如果將網頁解答全部複製貼上，輸入submit()，錯誤訊息如下： | Sourcing your script...

Joining, by = c("year", "month", "day", "hour", "origin") Joining, by = c("year", "month", "day", "hour", "origin") Joining, by = c("year", "month", "day", "hour", "origin") answer02.3 is wrong Factor levels not equal for column wind_speed

| Nice try, but that's not exactly what I was hoping for. Try again.

使用者名稱是英文的喔~ RVisualization-04-HW.R 參考網頁解答完成了， 但 輸入 hw() 是看不到解答的~

恭喜你家中有新成員!

回報一下，我也遇到 RVisualization-04-HW.R 輸入 hw() 無法看參考解答的問題，也是有下錯誤：

Error in file(con, "r") : cannot open the connection === Show Traceback 出現的部分： 4 file(con, "r") 3 readLines(.get_path(".hw")[2]) 2 strsplit(src, readLines(.get_path(".hw")[2])) at initLesson.R#26 1 hw() == end Traceback In addition: Warning message: In file(con, "r") : cannot open file 'NA': No such file or directory

我是Mac 使用者 Rstudio Version 1.0.44 R version 3.3.2

恭喜Wush大！

我的猜測是.Rds檔案在跨平台時出現問題

之後要找新的portable serialization format...

要上patch才能解決了，先麻煩幾位忍耐一下。
