订购“混合”向量（带字母的数字）

Question

我如何订购像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"并使用它对data.frame进行排序，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)并排序要获取的行（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

确保您使用的是最新发布的ggplot2的最新版本。事情的顺序在旧版本中一直很痛苦，尽管我没有在新版本中尝试过，但是我知道它已经被大量重写和改进，所以我希望他们能够解决这个问题。
