function in R Language is used to delete objects from the memory. It can be used with **rm()**`ls()`

function to delete all objects. `remove()`

function is also similar to `rm()`

function.

Syntax:rm(x)

Parameters:

x:Object name

**Example 1:**

`# R Program to remove ` `# objects from Memory ` ` ` `# Creating a vector ` `vec <` `-` `c(` `1` `, ` `2` `, ` `3` `, ` `4` `) ` `vec ` ` ` `# Creating a list ` `list1 ` `=` `list` `(` `"Number"` `=` `c(` `1` `, ` `2` `, ` `3` `), ` ` ` `"Characters"` `=` `c(` `"a"` `, ` `"b"` `, ` `"c"` `)) ` `list1 ` ` ` `# Creating a matrix ` `mat <` `-` `matrix(c(` `1` `:` `9` `), ` `3` `, ` `3` `) ` `mat ` ` ` `# Calling rm() Function ` `rm(list1) ` ` ` `# Calling ls() to check object list ` `ls() ` |
