Last update on December 21 2024 10:10:37 (UTC/GMT +8 hours)

Write a R program to create three vectors numeric data, character data and logical data. Display the content of the vectors and their type.

Sample Solution :

R Programming Code :

# Create a numeric vector 'a' with specified values
a = c(1, 2, 5, 3, 4, 0, -1, -3)

# Create a character vector 'b' with specified color names
b = c("Red", "Green", "White")

# Create a logical vector 'c' with specified boolean values
c = c(TRUE, TRUE, TRUE, FALSE, TRUE, FALSE)

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

# Print the data type of the vector 'a'
print(typeof(a))

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

# Print the data type of the vector 'b'
print(typeof(b))

# Print the contents of the logical vector 'c'
print(c)

# Print the data type of the vector 'c'
print(typeof(c))

Output:

[1]  1  2  5  3  4  0 -1 -3
[1] "double"
[1] "Red"   "Green" "White"
[1] "character"
[1]  TRUE  TRUE  TRUE FALSE  TRUE FALSE
[1] "logical"                         

Explanation:

• Create Numeric Vector a:
• a = c(1, 2, 5, 3, 4, 0, -1, -3)
• Defines a numeric vector a with the values: 1, 2, 5, 3, 4, 0, -1, -3.
• Create Character Vector b:
• b = c("Red", "Green", "White")
• Defines a character vector b with the values: "Red", "Green", "White".
• Create Logical Vector c:
• c = c(TRUE, TRUE, TRUE, FALSE, TRUE, FALSE)
• Defines a logical vector c with the values: TRUE, TRUE, TRUE, FALSE, TRUE, FALSE.
• Print Vector a:
• print(a)
• Displays the contents of vector a.
• Print Data Type of a:
• print(typeof(a))
• Shows the data type of vector a, which is "double" (numeric).
• Print Vector b:
• print(b)
• Displays the contents of vector b.
• Print Data Type of b:
• print(typeof(b))
• Shows the data type of vector b, which is "character".
• Print Vector c:
• print(c)
• Displays the contents of vector c.
• Print Data Type of c:
• print(typeof(c))
• Shows the data type of vector c, which is "logical".
