R Program to find Unique elements in Strings and Vectors

R Programming: Basic Exercise-11 with Solution

Write a R program to get the unique elements of a given string and unique numbers of vector.

Sample Solution :

R Programming Code :

# Assign a string to the variable str1
str1 = "The quick brown fox jumps over the lazy dog."

# Print a message indicating that the following output is the original string
print("Original vector(string)")

# Print the content of the string
print(str1)

# Print a message indicating that the following output will show unique elements of the string
print("Unique elements of the said vector:")

# Convert the string to lowercase and print unique characters
print(unique(tolower(str1)))

# Create a vector of numbers with some duplicates
nums = c(1, 2, 2, 3, 4, 4, 5, 6)

# Print a message indicating that the following output is the original number vector
print("Original vector(number)")

# Print the content of the number vector
print(nums)

# Print a message indicating that the following output will show unique elements of the number vector
print("Unique elements of the said vector:")

# Print unique numbers from the vector
print(unique(nums))

Output:

[1] "Original vector(string)"
[1] "The quick brown fox jumps over the lazy dog."
[1] "Unique elements of the said vector:"
[1] "the quick brown fox jumps over the lazy dog."
[1] "Original vector(number)"
[1] 1 2 2 3 4 4 5 6
[1] "Unique elements of the said vector:"
[1] 1 2 3 4 5 6                         

Explanation:

• str1 = "The quick brown fox jumps over the lazy dog.": Assigns a string to the variable str1.
• print("Original vector(string)"): Prints the label for the original string.
• print(str1): Displays the content of the string str1.
• print("Unique elements of the said vector:"): Prints a label indicating the unique elements in the string.
• print(unique(tolower(str1))): Converts all characters in str1 to lowercase and prints the unique elements from the string.
• nums = c(1, 2, 2, 3, 4, 4, 5, 6): Creates a vector nums containing a set of numeric values, some of which are duplicates.
• print("Original vector(number)"): Prints the label for the original numeric vector.
• print(nums): Displays the content of the numeric vector nums.
• print("Unique elements of the said vector:"): Prints a label indicating the unique elements in the numeric vector.
• print(unique(nums)): Extracts and prints the unique elements from the vector nums.
