我正在使用從該頁面例如重新排序:http://kohske.wordpress.com/2010/12/29/faq-how-to-order-the-factor-variables-in-ggplot2/但代碼似乎並不奏效:爲什麼因子變量不是R中
d <- data.frame(Team1=c("Cowboys", "Giants", "Eagles", "Redskins"), Win=c(20, 13, 9, 12))
d
Team1 Win
1 Cowboys 20
2 Giants 13
3 Eagles 9
4 Redskins 12
>
d$Team1
[1] Cowboys Giants Eagles Redskins
Levels: Cowboys Eagles Giants Redskins
>
>
d$Team3 <- reorder(d$Team1, d$Win)
d
Team1 Win Team3
1 Cowboys 20 Cowboys
2 Giants 13 Giants
3 Eagles 9 Eagles
4 Redskins 12 Redskins
>
>
d$Team3
[1] Cowboys Giants Eagles Redskins
Levels: Cowboys Eagles Giants Redskins
>
>
d[order(d$Team1),]
Team1 Win Team3
1 Cowboys 20 Cowboys
3 Eagles 9 Eagles
2 Giants 13 Giants
4 Redskins 12 Redskins
>
d[order(d$Team3),]
Team1 Win Team3
1 Cowboys 20 Cowboys
3 Eagles 9 Eagles
2 Giants 13 Giants
4 Redskins 12 Redskins

的Team3列是相同TEAM1儘管reoder命令。哪裏有問題。謝謝你的幫助。
編輯:
levels(d$Team1)
[1] "Cowboys" "Eagles" "Giants" "Redskins"
>
levels(d$Team3)
[1] "Cowboys" "Eagles" "Giants" "Redskins"
>
當我運行代碼,我沒有得到'結果你正在顯示的「d $ Team3」。我看到水平重新排序。您似乎也在混合'order'(data.frame中變量的排序順序)和'reorder'(與變量中每個整數值對應的'levels')。也許這也造成了一些困惑。 – Thomas
我正在使用命令來測試級別是否已重新排序。我嘗試重新啓動R,但問題依然存在。我在Linux Debian Stable和版本3.1.0窗口上使用R.version 2.15.1。 – rnso
