Overview
The goal of hansen is to provide the datasets used in the exercises of the book Econometrics by Bruce E. Hansen following the Tidy Data principles.
The datasets were already processed and tidied following the steps in the original code by Professor Hansen. The goal is to go directly to writing functions in C++.
Installation
You can install the development version of hansen like so:
remotes::install_github("pachadotdev/hansen")
Usage
As an example, here is how to get the description for the data from Mankiw, Romer and Well (1992), which is a dataset for economic growth analysis:
library(hansen)
#>
#> Attaching package: 'hansen'
#> The following object is masked from 'package:stats':
#>
#> influence
str(mrw1992)
#> Classes 'tbl_df', 'tbl' and 'data.frame': 121 obs. of 10 variables:
#> $ country : chr "Algeria" "Angola" "Benin" "Botswana" ...
#> ..- attr(*, "label")= chr "country name"
#> $ n : Factor w/ 2 levels "No","Yes": 2 2 2 2 2 2 2 2 2 2 ...
#> $ i : Factor w/ 2 levels "No","Yes": 2 1 1 2 1 1 2 1 1 1 ...
#> $ o : Factor w/ 2 levels "No","Yes": 1 1 1 1 1 1 1 1 1 1 ...
#> $ y60 : num 2485 1588 1116 959 529 ...
#> ..- attr(*, "label")= chr "GDP60"
#> $ y85 : num 4371 1171 1071 3671 857 ...
#> ..- attr(*, "label")= chr "GDP85"

#> $ pop_growth: num 2.6 2.1 2.4 3.2 0.9 ...
#> ..- attr(*, "label")= chr "pop growth"
#> $ invest : num 24.1 5.8 10.8 28.3 12.7 ...
