R Programming - Find Elements Present in Two Given Data Frames

R Programming: Data frame Exercise-20 with Solution

Write a R program to find elements which are present in two given data frames.

Sample Solution:

R Programming Code:

# Create vector 'a' with elements "a", "b", "c", "d", "e"
a = c("a", "b", "c", "d", "e")

# Create vector 'b' with elements "d", "e", "f", "g"
b = c("d", "e", "f", "g")

# Print a message indicating the original dataframes
print("Original Dataframes")

# Print the contents of vector 'a'
print(a)

# Print the contents of vector 'b'
print(b)

# Print a message indicating the elements present in both dataframes
print("Elements which are present in both dataframe:")

# Find and store elements common to both vectors 'a' and 'b'
result = intersect(a, b)

# Print the elements that are present in both vectors
print(result)

Output:

[1] "Original Dataframes"
[1] "a" "b" "c" "d" "e"
[1] "d" "e" "f" "g"
[1] "Elements which are present in both dataframe:"
[1] "d" "e"

Explanation:

• Create Vector 'a':
• a = c("a", "b", "c", "d", "e")
• Defines a vector a containing the elements "a", "b", "c", "d", and "e".
• Create Vector 'b':
• b = c("d", "e", "f", "g")
• Defines a vector b containing the elements "d", "e", "f", and "g".
• Print Original Dataframes Message:
• print("Original Dataframes")
• Prints the message "Original Dataframes" to indicate the start of the output for the vectors.
• Print Vector 'a':
• print(a)
• Displays the contents of vector a.
• Print Vector 'b':
• print(b)
• Displays the contents of vector b.
• Print Common Elements Message:
• print("Elements which are present in both dataframe:")
• Prints the message "Elements which are present in both dataframe:" to indicate the following output will show common elements.
• Find Intersection of Vectors 'a' and 'b':
• result = intersect(a, b)
• Computes the intersection of vectors a and b, which gives the elements common to both vectors, and stores the result in the variable result.
• Print Common Elements:
• print(result)
• Displays the elements that are present in both vectors a and b.
