Test Whether a Vector contains a specified element in R Programming
Write a R program to test whether a given vector contains a specified element.
Sample Solution :
R Programming Code :
# Create a numeric vector 'x' with elements 10, 20, 30, 25, 9, and 26
x = c(10, 20, 30, 25, 9, 26)
# Print a message indicating the display of the original vector
print("Original Vectors:")
# Print the contents of vector 'x'
print(x)
# Print a message indicating the test for the presence of the element 25
print("Test whether above vector contains 25:")
# Test if the vector 'x' contains the element 25 and print the result
print(is.element(25, x))
# Print a message indicating the test for the presence of the element 56
print("Test whether above vector contains 56:")
# Test if the vector 'x' contains the element 56 and print the result
print(is.element(56, x))
Output:
[1] "Original Vectors:" [1] 10 20 30 25 9 26 [1] "Test whether above vector contains 25:" [1] TRUE [1] "Test whether above vector contains 56:" [1] FALSE
Explanation:
- x = c(10, 20, 30, 25, 9, 26): Creates a numeric vector x with the elements 10, 20, 30, 25, 9, and 26.
- print("Original Vectors:"): Prints the label "Original Vectors:" to indicate that the following output will show the vector x.
- print(x): Prints the contents of vector x.
- print("Test whether above vector contains 25:"): Prints the label "Test whether above vector contains 25:" to indicate that the following output will show whether the vector x contains the element 25.
- print(is.element(25, x)): Checks if the element 25 is present in vector x and prints the result, which will be TRUE if it is present.
- print("Test whether above vector contains 56:"): Prints the label "Test whether above vector contains 56:" to indicate that the following output will show whether the vector x contains the element 56.
- print(is.element(56, x)): Checks if the element 56 is present in vector x and prints the result, which will be FALSE if it is not present.
