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.
name = "Python";
num1 = 8;
num2 = 1.5
nums = c(10, 20, 30, 40, 50, 60)
print(ls())
## [1] "defaultW" "name" "num1" "num2" "nums"
print("Details of the objects in memory: \n")
## [1] "Details of the objects in memory: \n"
print(ls.str())
## defaultW : int 0
## name : chr "Python"
## num1 : num 8
## num2 : num 1.5
## nums : num [1:6] 10 20 30 40 50 60
