R 根据自己的意愿对向量进行排序

Question

df.sorted <- c("binned_walker1_1.grd", "binned_walker1_2.grd", "binned_walker1_3.grd",
    "binned_walker1_4.grd", "binned_walker1_5.grd", "binned_walker1_6.grd",
    "binned_walker2_1.grd", "binned_walker2_2.grd", "binned_walker3_1.grd",
    "binned_walker3_2.grd", "binned_walker3_3.grd", "binned_walker3_4.grd",
    "binned_walker3_5.grd", "binned_walker4_1.grd", "binned_walker4_2.grd",
    "binned_walker4_3.grd", "binned_walker4_4.grd", "binned_walker4_5.grd",
    "binned_walker5_1.grd", "binned_walker5_2.grd", "binned_walker5_3.grd",
    "binned_walker5_4.grd", "binned_walker5_5.grd", "binned_walker5_6.grd",
    "binned_walker6_1.grd", "binned_walker7_1.grd", "binned_walker7_2.grd",
    "binned_walker7_3.grd", "binned_walker7_4.grd", "binned_walker7_5.grd",
    "binned_walker8_1.grd", "binned_walker8_2.grd", "binned_walker9_1.grd",
    "binned_walker9_2.grd", "binned_walker9_3.grd", "binned_walker9_4.grd",
    "binned_walker10_1.grd", "binned_walker10_2.grd", "binned_walker10_3.grd")

人们会期望这个向量的顺序是 1:length(df.sorted) ，但情况似乎并非如此。看起来 R 在内部根据其逻辑对向量进行排序，但非常努力地以创建它的方式显示它(并在输出中看到)。

order(df.sorted)
 [1] 37 38 39  1  2  3  4  5  6  7  8  9 10 11 12 13 14 15 16 17 18 19 20 21 22
[26] 23 24 25 26 27 28 29 30 31 32 33 34 35 36

有没有办法将订单“重置”为 1:length(df.sorted) ?这样，排序和向量的输出将同步。

Answer 1

使用 mixedsort (或) mixedorder gtools 包中的函数:

require(gtools)
mixedorder(df.sorted)
 [1]  1  2  3  4  5  6  7  8  9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27
[28] 28 29 30 31 32 33 34 35 36 37 38 39
