我如何訂購像c("7","10a","10b","10c","8","9","11c","11b","11a","12") -> alph在alph[1] "7","8","9","10a","10b","10c","11a","11b","11c","12"并使用它對data.frame進行排序，例如V1 <- c("A","A","B","B","C","C","D","D","E","E")V2 <- 2:1 V3 <- alph
df <- data.frame(V1,V2,V3)并排序要獲取的行（先依次排序V2和V3） V1 V2 V3
C 1 9A 1 10a
B 1 10c
D 1 11b
E 1 12A 2 7C 2 8B 2 10b
E 2 11a
D 2 11c

確保您使用的是最新發布的ggplot2的最新版本。事情的順序在舊版本中一直很痛苦，盡管我沒有在新版本中嘗試過，但是我知道它已經被大量重寫和改進，所以我希望他們能夠解決這個問題。
