Get List of Data Sets in Package in R (Example)

In this article, I’ll illustrate how to return a list of data sets in a particular package in the R programming language.

The tutorial looks as follows:

Let’s do this!

Example: Return All Data Sets Contained in a Package Using data() Function

This section shows how to get a list of all data sets that are provided by a certain add-on package.

For this example, we’ll use the ggplot2 package. We first have to install and load ggplot2:

install.packages("ggplot2")                                # Install & load ggplot2
library("ggplot2")

In the next step, we can apply the data() function to create a list of data sets that are contained in ggplot2:

data_list <- data(package = "ggplot2")$results[ , "Item"]  # Create list of packages
data_list                                                  # Print list of packages
#  [1] "diamonds"       "economics"      "economics_long" "faithfuld"      "luv_colours"    "midwest"        "mpg"            "msleep"         "presidential"   "seals"          "txhousing"

As you can see, the ggplot2 package provides many different data sets. One of them is the diamonds data set.

We can load this data set as shown below:

data(diamonds)                                             # Load diamonds data set
head(diamonds)                                             # Print head of diamonds data set

By executing the previous R programming syntax, we have returned the first six rows of the diamonds data set.
