What is the Workspace?

• The workspace in R refers to the environment that contains all user-defined variables, functions, and data.

• It represents your current R session’s memory space.

Listing Objects

• Use ls() to list all objects in the workspace.

• ls() can be customized to show objects that meet specific conditions.

# Example: Create a few objects
a <- 3.14
b <- 42L

# List all objects
ls()

## [1] "a" "b"

Using rm(list = ls())

• rm(list = ls()) chains toether two built-in functions, rm() and ls(), to clear all objects from the workspace.

• The rm() function is used to remove objects from the R environment.

• The ls() function lists all objects in the current R environment

# Example: Create a few objects
a <- 3.14
b <- 42L

# List all objects
ls()

## [1] "a" "b"

# remove all objects
rm(list = ls())

# List all objects again
ls()

## character(0)

Keeping a Clean Workspace

• Regularly use ls() to review, and rm() to remove unnecessary objects.

• Keep your workspace organized to improve efficiency and reduce errors and bugs.
