R Program to get and display details of objects in memory

R Programming: Basic Exercise-2 with Solution

Write a R program to get the details of the objects in memory.

Sample Solution :

R Programming Code :

# Assign the string "Python" to the variable `name`
name = "Python"

# Assign the integer value 10 to the variable `n1`
n1 =  10

# Assign the numeric value 0.5 to the variable `n2`
n2 =  0.5

# Create a vector `nums` containing the numbers 10, 20, 30, 40, 50, 60
nums = c(10, 20, 30, 40, 50, 60)

# Print the names of all objects currently in the environment
print(ls())

# Print a message indicating that details of the objects in memory will be shown
print("Details of the objects in memory:")

# Print a detailed list of all objects in memory, including their structure
print(ls.str()) 

Output:

[1] "n1"   "n2"   "name" "nums"
[1] "Details of the objects in memory:"
n1 :  num 10
n2 :  num 0.5
name :  chr "Python"
nums :  num [1:6] 10 20 30 40 50 60                         

Explanation:

• Define Variables:
• name = "Python": Assigns the string "Python" to the variable name.
• n1 = 10: Assigns the integer 10 to the variable n1.
• n2 = 0.5: Assigns the floating-point number 0.5 to the variable n2.
• nums = c(10, 20, 30, 40, 50, 60): Creates a vector named nums containing the numbers 10, 20, 30, 40, 50, 60.
• List All Objects in Memory:
• print(ls()): Displays the names of all objects currently stored in memory (i.e., name, n1, n2, nums).
• Print Object Details:
• print("Details of the objects in memory:"): Prints a descriptive message.
• print(ls.str()): Displays detailed information about each object in memory, such as their types and contents.
