如何通过属性“名称"对向量进行排序在R中，但保持第一个元素不变? [英] How do I order a vector by attribute "names" in R but keeping the first element constant?

问题描述

说我有一个向量及其名称，如下所示:

Say I have a vector and its name as follows:

   vct <- c(67, "apple", 88, "orange", 71)
names(vct) <- c("c1", "b2", "d66", "a65", "a11")

现在，我希望第一个元素67保持原样，并按其名称的顺序对其余元素进行排序.这样看来:"67"，"71"，橙色"，苹果"，"88".

Now I want the first element 67 to be as is and order the rest on the order of their names. So that it appears: "67", "71", "orange", "apple", "88".

推荐答案

您可以使用 -1 排除第一个，其余按其名称排序，加1和 c与1:

You can use -1 for to exclude the first one, order the rest by it's name, add 1 and c with 1:

vct[c(1, order(names(vct)[-1])+1)]
#      c1      a11      a65       b2      d66 
#    "67"     "71" "orange"  "apple"     "88"
