R Programming: Convert a given List to Vector

Last update on December 21 2024 10:11:31 (UTC/GMT +8 hours)

Write a R program to convert a given list to vector.

Sample Solution :

R Programming Code :

# Create the first list containing numbers
n1 = list(1,2,3)

# Create the second list containing numbers
c1 = list(4,5,6)

# Print the message indicating the start of the original lists
print("Original lists:")

# Print the first list
print(n1)

# Print the second list
print(c1)

# Print the message indicating the start of conversion to vectors
print("Convert the lists to vectors:")

# Convert the first list to a vector
v1 = unlist(n1)

# Convert the second list to a vector
v2 = unlist(c1)

# Print the vector created from the first list
print(v1)

# Print the vector created from the second list
print(v2)

# Print the message indicating the start of adding two vectors
print("Add two vectors:")

# Add the two vectors element-wise
v = v1 + v2

# Print the resulting vector after addition
print("New vector:")

# Print the new vector
print(v)

Output:

[1] "Original lists:"
[[1]]
[1] 1

[[2]]
[1] 2

[[3]]
[1] 3

[[1]]
[1] 4

[[2]]
[1] 5

[[3]]
[1] 6

[1] "Convert the lists to vectors:"
[1] 1 2 3
[1] 4 5 6
[1] "Add two vectors:"
[1] "New vector:"
[1] 5 7 9                         

Explanation:

• Create Lists:
• n1 = list(1,2,3) creates a list n1 containing the numbers 1, 2, and 3.
• c1 = list(4,5,6) creates a list c1 containing the numbers 4, 5, and 6.
• Print Original Lists:
• print("Original lists:") prints a message indicating that the original lists will be displayed.
• print(n1) prints the contents of the list n1.
• print(c1) prints the contents of the list c1.
• Convert Lists to Vectors:
• print("Convert the lists to vectors:") prints a message indicating that the conversion process will begin.
• v1 = unlist(n1) converts the list n1 into a vector v1.
• v2 = unlist(c1) converts the list c1 into a vector v2.
• Print Vectors:
• print(v1) prints the vector v1 created from n1.
• print(v2) prints the vector v2 created from c1.
• Add Two Vectors:
• print("Add two vectors:") prints a message indicating that the addition of vectors will be shown.
• v = v1 + v2 performs element-wise addition of vectors v1 and v2, resulting in a new vector v.
• Print New Vector:
• print("New vector:") prints a message indicating that the new vector will be displayed.
• print(v) prints the result of the vector addition.
