R语言如何通过列的内容对R数据框架进行排序

在这篇文章中，我们将讨论如何在R编程语言中根据列的内容对DataFrame进行排序。我们可以使用order()函数来实现。order()函数使用所提供的参数返回一个排列组合，将其第一个参数重新排列成升序或降序，并通过进一步的参数打破联系。

语法： order(x, decreasing = TRUE/FALSE, na.last = TRUE or FALSE, method = c(“auto”, “shell”, “quick”, “radix”)

参数

x：数据帧、矩阵或向量
decreasing ：TRUE则按降序排序/FALSE则按升序排序。
na.last。TRUE，则将NA指数放在最后/FALSE，则将NA指数放在前面。
method：排序方法。

返回： 返回一个将其第一个参数重新排列成数据框、向量、矩阵等的升序或降序的排列方式。

示例1 :

gfg_data <- data.frame(
  Country = c("France","Spain","Germany","Spain","Germany",
              "France","Spain","France","Germany","France"),
   
  age = c(44,27,30,38,40,35,52,48,45,37),
   
  salary = c(6000,5000,7000,4000,8000),
   
  Purchased=c("No","Yes","No","No","Yes","Yes","No","Yes",
              "No","Yes")
)
 
gfg_data[order(gfg_data$Country),]

输出

如何通过列的内容对R数据框架进行排序？

例2 :

gfg_data <- data.frame(
  Country = c("France","Spain","Germany","Spain","Germany",
              "France","Spain","France","Germany","France"),
     
  age = c(44,27,30,38,40,35,52,48,45,37),
     
  salary = c(6000,5000,7000,4000,8000),
     
  Purchased=c("No","Yes","No","No","Yes","Yes","No","Yes",
              "No","Yes")
)
 
gfg_data[order(gfg_data$age),]

输出
