# 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**: ```R if(!require("remotes")){ install.packages("remotes") } remotes::install_github("leeper/webuse") ``` [![Build Status](https://travis-ci.org/leeper/webuse.svg?branch=master)](https://travis-ci.org/leeper/webuse) [![CRAN Version](https://www.r-pkg.org/badges/version/webuse)](https://CRAN.R-project.org/package=webuse) ![Downloads](https://cranlogs.r-pkg.org/badges/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`: ```r 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: ```r library("webuse") webuse("auto", version = 15, envir = parent.frame()) head(auto) ``` ``` ## # A tibble: 6 x 12 ## make price mpg rep78 headroom trunk weight length turn displacement gear_ratio foreign ## ## 1 AMC Concord 4099. 22. 3. 2.50 11. 2930. 186. 40. 121. 3.58 0 ## 2 AMC Pacer 4749. 17. 3. 3.00 11. 3350. 173. 40. 258. 2.53 0 ## 3 AMC Spirit 3799. 22.
