Create Vectors of Numeric, Complex, Logical, and Character Types in R

R Programming: Vector Exercise-1 with Solution

Write a R program to create a vector of a specified type and length. Create vector of numeric, complex, logical and character types of length 6.

Sample Solution :

R Programming Code :

# Create a numeric vector of length 5 initialized with zeros
x = vector("numeric", 5)
# Print the label for the numeric vector
print("Numeric Type:")
# Print the numeric vector
print(x)

# Create a complex vector of length 5 initialized with zeros
c = vector("complex", 5)
# Print the label for the complex vector
print("Complex Type:")
# Print the complex vector
print(c)

# Create a logical vector of length 5 initialized with FALSE
l = vector("logical", 5)
# Print the label for the logical vector
print("Logical Type:")
# Print the logical vector
print(l)

# Create a character vector of length 5 initialized with empty strings
chr = vector("character", 5)
# Print the label for the character vector
print("Character Type:")
# Print the character vector
print(chr)

Output:

[1] "Numeric Type:"
[1] 0 0 0 0 0
[1] "Complex Type:"
[1] 0+0i 0+0i 0+0i 0+0i 0+0i
[1] "Logical Type:"
[1] FALSE FALSE FALSE FALSE FALSE
[1] "Character Type:"
[1] "" "" "" "" ""                         

Explanation:

• x = vector("numeric", 5):
• Creates a numeric vector x of length 5, initialized with zeros.
• print("Numeric Type:"):
• Prints the label "Numeric Type:" to indicate the following output is for the numeric vector.
• print(x):
• Prints the numeric vector x.
• c = vector("complex", 5):
• Creates a complex vector c of length 5, initialized with zeros (complex type).
• print("Complex Type:"):
• Prints the label "Complex Type:" to indicate the following output is for the complex vector.
• print(c):
• Prints the complex vector c.
• l = vector("logical", 5):
• Creates a logical vector l of length 5, initialized with FALSE.
• print("Logical Type:"):
• Prints the label "Logical Type:" to indicate the following output is for the logical vector.
• print(l):
• Prints the logical vector l.
• chr = vector("character", 5):
• Creates a character vector chr of length 5, initialized with empty strings.
• print("Character Type:"):
• Prints the label "Character Type:" to indicate the following output is for the character vector.
• print(chr):
• Prints the character vector chr
