Import Stata 'webuse' Datasets

This package provides a Stata-style webuse() function for importing named datasets from Stata's online collection.

Package Installation

This package can be installed from R using install.packages("webuse") or from GitHub using remotes:

if(!require("remotes")){
    install.packages("remotes")
}
remotes::install_github("leeper/webuse")

Code Examples

Functionality is simple. Load webuse and then access any online Stata dataset using the webuse() function. This will assign the named dataset from Stata 15 to the .GlobalEnv:

library("webuse")
webuse("auto")
head(auto)

As an option, you can specify the Stata version of the dataset and the environment via version and envir parameters:

library("webuse")
webuse("auto", version = 15, envir = parent.frame())
head(auto)
