How to sort R DataFrame by the contents of a column ?

In this article, we will discuss how to sort DataFrame by the contents of the column in R Programming language. We can use the order() function for the same. order() function with the provided parameters returns a permutation that rearranges its first argument into ascending or descending order, breaking ties by further arguments. 

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

Parameters:

• x: data-frames, matrices, or vectors
• decreasing: TRUE then sort in descending order / FALSE then sort in ascending order.
• na.last: TRUE then NA indices are put at last / FALSE then NA indices are put first.
• method: sorting method.

Return: returns a permutation that rearranges its first argument into ascending or descending order of the data frame, vector, matrix, etc.

Example1:

R

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),]

Output:

Example2:

R

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),]

Output:
