R Programming: Get the length of the first two vectors of a list

Last update on December 21 2024 10:11:27 (UTC/GMT +8 hours)

Write a R program to get the length of the first two vectors of a given list.

Sample list: (g1 = 1:10, g2 = "R Programming", g3 = "HTML")

Sample Solution :

R Programming Code :

# Create a list with three elements
list1 = list(g1 = 1:10, g2 = "R Programming", g3 = "HTML")

# Print a message indicating that the original list will be shown
print("Original list:")

# Print the contents of the original list
print(list1)

# Print a message indicating that the length of 'g1' and 'g2' will be shown
print("Length of the vector 'g1' and 'g2' of the said list")

# Print the length of the first vector in the list
print(length(list1$g1))

# Print the length of the second vector in the list
print(length(list1$g2))

Output:

[1] "Original list:"
$g1
 [1]  1  2  3  4  5  6  7  8  9 10

$g2
[1] "R Programming"

$g3
[1] "HTML"

[1] "Length of the vector 'g1' and 'g2' of the said list"
[1] 10
[1] 1                         

Explanation:

• Create a List: list1 = list(g1 = 1:10, g2 = "R Programming", g3 = "HTML") creates a list named list1 with three elements: g1 (a vector of integers from 1 to 10), g2 (a character string "R Programming"), and g3 (a character string "HTML").
• Print Original List: print("Original list:") followed by print(list1) displays the message "Original list:" and then prints the contents of list1.
• Print Lengths of Vectors: print("Length of the vector 'g1' and 'g2' of the said list") is followed by print(length(list1$g1)) and print(length(list1$g2)) to show the lengths of the vectors g1 and g2. list1$g1 has a length of 10, and list1$g2 has a length of 1.
