Print All Data Objects in Workspace in R (2 Examples)

In this R tutorial you’ll learn how to return all data objects in the RStudio workspace.

Let’s dig in:

Construction of Example Data

The following data will be used as basement for this R programming tutorial:

data <- data.frame(x = 1:5,        # Create example data
                   y = 9:5)
vec <- 1:10                        # Create example vector

Let’s print these data!

Example 1: Print Names of All Data Objects in Workspace Using ls() Function

The following R programming code demonstrates how to get the names of all objects in the R programming workspace (or environment).

For this task, we can use the ls function as shown below:

ls()                               # Print names of data objects
# [1] "data" "vec"

The previous output of the RStudio console shows the names of all data objects that are currently stored in our workspace.

Example 2: Print Content of All Data Objects in Workspace Using ls() & mget() Functions

In Example 2, I’ll show how to return the content of all data objects in a list.

For this, we can use the mget function and the ls function as shown in the following R syntax:

mget(ls())                         # Print content of data objects
# $data
#   x y
# 1 1 9
# 2 2 8
# 3 3 7
# 4 4 6
# 5 5 5
# 
# $vec
#  [1]  1  2  3  4  5  6  7  8  9 10

As you can see, our data objects data and vec contain a data frame and a numeric vector.
