ggplot2 37% 做不出來

| 請同學利用group_by和summarise計算各種sex類別的個數。

hsb %>%

• group_by(sex) %>%
• summarise(a=n()) Source: local data frame [2 x 2]

 sex     a

(fctr) (int) 1 female 109 2 male 91

我認為我答案是對的，但是，不給過~~

你確認看看colnames呢？

[ningchencontact]

hsb %>%

• group_by(sex) %>%
• summarise(count=n()) Source: local data frame [2 x 2]

 sex count

(fctr) (int) 1 female 109 2 male 91

我有改了一下 欄位應該是對的 但還是過不去

[wush978]

我也不知道為什麼你過不去（但是其他人可以）

麻煩貼上你的錯誤訊息喔！

ps. 沒過的話，應該會印出錯誤訊息

我按skip 跟 "Press Enter when you are ready to continue..."

hsb %>%

• group_by(sex) %>%

• summarise(count=n()) Source: local data frame [2 x 2]

  sex count (fctr) (int) 1 female 109 2 male 91

  skip()

| I just sourced the following script, which demonstrates one | possible solution.

Press Enter when you are ready to continue...

| Not exactly. Give it another go.

skip()

| I just sourced the following script, which demonstrates one | possible solution.

Press Enter when you are ready to continue...

| You're close...I can feel it! Try it again.

1. 檢查一下有沒有存檔喔
2. 檢查一下檔案裡面的程式碼有沒有syntax error

方式：ctrl + A 後把內容通通送到console, 看R有沒有噴錯
