此題目中 未解釋何謂是expression(前幾題也沒解釋)
建議在此題前面加上assignment 跟 expression的解釋
以方便學員了解跟作答

| 在R
| 中,c()可以接受任意數量的的向量參數,並且會依照順序把它們
| 串接成一個單一向量。舉例來說:c(x, | 1)會在剛剛我們建立的x 後面 再接一個1
| 。而c(x, 2, 3)則會在x 之後接上2 和3
| 。請同學依照這個要領,
| 撰寫一個expression,內容是建立一個在x
| 後面接上x 的向量。

這其實牽涉到閱讀教材的順序。
我應該要在前面標示1, 2, 3, ...

我記得在 Introduction 的時候有解釋expression,請 @agogomei01 幫我看看如果加上閱讀順序後(具體的更改內容在 #22 ),是否算是解決這個問題。
