List of Built in Datasets in R

R Datasets
R Built-in Datasets

R has numerous datasets that are built-in and these datasets are available in a R package called “R Datasets Package“. This is maintained by R Core team and available with base installation of R. We can find the list of built-in datasets readily available in R using R function data().

Find out Builtin datasets in R with data()

If we use data() function without any arguments, we will get the list of built-in datasets.

data()

data() opens a tab/window listing all the built-in datasets. In total, we have 104 built-in datasets in R.

R Built-in Datasets

List of datasets in R Datasets Package with help()

We can also get the list of all Builtin datasets in R using help() function. 

help(package="datasets")

Here we specify the datasets R package name and it opens a help window like this.

Builtin Datasets in R Datasets Package

List of datasets in a specific R Package with data()

We can list the available dataset in any package as follows.

# list available datasets in ggplot2 package
data(package="ggplot2")
List Datasets in a Specific R Package

List All Datasets from all available R packages

To list all available datasets from all R package we have available/installed in your computer is use the data() function with the following argument.

# how to list all datasets from all installed packages
data(package = .packages(all.available = TRUE))

Accessing Built-In Dataset in R

We can directly access the builtin datasets using the name of the datasets

# access built-in dataset by its name

Accessing a dataset from a R Package

We can access a dataset from a R package using the pattern packageName::datasetName. In this example below, we get storms data from dplyr package.

# access a dataset available in a package
dplyr::storms

## # A tibble: 10,010 x 13
##    name   year month   day  hour   lat  long status category  wind pressure
