Here we are explaining how to write an R program to get the details of the objects in memory. Here we are using built-in functions ls() means list objects for this calculation. The ls() helps to return a vector of character strings with the names of the objects in the specified environment. If we called this function without arguments it will give the data sets and functions that a user has defined. And the ls.str is used for a long listing based on the str.
Below are the steps used in the R program to get the details of the objects in memory. In this R program, we directly give the values to variables name,num1,num2, nums. And print the function result. Here the variable name is assigned with a string num1 with an integer value,num2 with floating value, and nums with vector values.
STEP 1: Assign variable name,num1,num2, nums with corresponding values
STEP 2: Call the built-in functions ls() for a listing of objects
STEP 3: First print given objects
STEP 4: Call the built-in functions ls.str() for string based long listing
name = "Python"; num1 = 8; num2 = 1.5 nums = c(10, 20, 30, 40, 50, 60) print(ls()) print("Details of the objects in memory:") print(ls.str())
 "num1" "num2" "name" "nums"  "Details of the objects in memory:" num1 : num 8 num2 : num 1.5 name : chr "Python" nums : num [1:6] 10 20 30 40 50 60
