Sorting of a Vector in R Programming – sort() Function
In R Programming Language we can sort a vector in ascending or descending order using the sort()
function. The sort()
function returns a sorted version of the input vector.
sort()
function in is used to sort a vector by its values. It takes the Boolean value as an argument to sort in ascending or descending order.
Syntax:
sort(x, decreasing, na.last)
Parameters:x: Vector to be sorted
- decreasing: Boolean value to sort in descending order
- na.last: Boolean value to put NA at the end
R program to sort a vector
Example 1:
R
# Creating a vector x <- c (7, 4, 3, 9, 1.2, -4, -5, -8, 6, NA ) # Calling sort() function sort (x) |
Output:
[1] -8.0 -5.0 -4.0 1.2 3.0 4.0 6.0 7.0 9.0
Example 2:
R
# Creating a vector x <- c (7, 4, 3, 9, 1.2, -4, -5, -8, 6, NA ) # Calling sort() function # to print in decreasing order sort (x, decreasing = TRUE ) # Calling sort() function # to print NA at the end sort (x, na.last = TRUE ) |
Output:
[1] 9.0 7.0 6.0 4.0 3.0 1.2 -4.0 -5.0 -8.0
[1] -8.0 -5.0 -4.0 1.2 3.0 4.0 6.0 7.0 9.0 NA
Example 3:
R
# Create a character vector names <- c ( "Vipul" , "Raj" , "Singh" , "Jhala" ) # Sort the vector in alphabetical order sorted_names <- sort (names) print (sorted_names) |
Output:
[1] "Jhala" "Raj" "Singh" "Vipul"
