R Programming: Create a List Containing 15 Capital Letters Starting from 'E'

Last update on June 05 2025 12:58:25 (UTC/GMT +8 hours)

Write a R program to create a list named s containing sequence of 15 capital letters, starting from ‘E’.

Sample Solution :

R Programming Code :

# Create a list named 'l' containing a sequence of 15 capital letters, starting from 'E'
l = LETTERS[match("E", LETTERS):(match("E", LETTERS)+15)]

# Print the message indicating the content of the list
print("Content of the list:")

# Print a description of the sequence of letters in the list
print("Sequence of 15 capital letters, starting from ‘E’-")

# Print the list 'l'
print(l)

Output:

[1] "Content of the list:"
[1] "Sequence of 15 capital letters, starting from ‘E’-"
 [1] "E" "F" "G" "H" "I" "J" "K" "L" "M" "N" "O" "P" "Q" "R" "S" "T              

Explanation:

• Create a List l:
• LETTERS is a built-in R vector containing all uppercase letters from A to Z.
• match("E", LETTERS) finds the position of "E" in the LETTERS vector, which is 5.
• LETTERS[match("E", LETTERS):(match("E", LETTERS)+15)] selects a subset of LETTERS starting from "E" and includes the next 15 letters.
• The result is a vector of 15 letters starting from "E" through "T".
• Print Message:
• print("Content of the list:") outputs the text "Content of the list:" to indicate what will be displayed next.
• Print Description:
• print("Sequence of 15 capital letters, starting from ‘E’-") provides a description of the content of the list.
• Print List:
• print(l) displays the list l which contains the sequence of 15 capital letters starting from "E".
