R Program to list the distinct values from a given vector

How to list the distinct values from a given vector

Here we are explaining how to write an R program to list the distinct values from a given vector. Here we are using a built-in function unique() for this finding. This function helps to find the distinct or unique values from the vector by eliminating duplicate values. The syntax of this function is

unique(x)

Here x is the vector, matrix, or data frame, returns a similar object whose duplicate elements need to be eliminated.

How to list the distinct values from a given vector in the R program

Below are the steps used in the R program to get the distinct values from a given vector. In this R program, we directly give the values to built-in functions. For that first, we consider the variable A in which vector value is assigned. Finally, call the unique function as unique(A) for finding the distinct element.

ALGORITHM

  • STEP 1: Assign variable A with vector values
  • STEP 2: First print original vector values
  • STEP 3: Call the function unique as unique(A)
  • STEP 4: print the result of the function

R Source Code

A = c(25, 25, 10, 15, 20, 20, 30, 40)

print("Original vector:")
## [1] "Original vector:"
print(A)
## [1] 25 25 10 15 20 20 30 40
print("Distinct values of the vector:")
## [1] "Distinct values of the vector:"
print(unique(A))
## [1] 25 10 15 20 30 40

R Source Code

A = c(5, 2, 1, 8, 5, 4, 3, 4)

print("Original vector:")
## [1] "Original vector:"
print(A)
## [1] 5 2 1 8 5 4 3 4
print("Distinct values of the vector:")
## [1] "Distinct values of the vector:"
print(unique(A))
## [1] 5 2 1 8 4 3
