Graduate students new to both PhD level econometrics and R may find the introduction to both challenging. One major challenge can be finding the empirical data to complete a Problem Set and then loading it into R.
The hayashir data package intends to lighten the load on readers of Hayashi’s “Econometrics” who want to follow the empirical parts of the text using R. The package contains all data used in the book and documentation for each data set is included. Once the package is installed and loaded, all data are ready to use with minimal fuss.
Installation
The hayashir package can be installed using the package devtools. After installing devtools, hayashir is installed by entering:
# install devtools if not already installed
# install.packages(devtools)
devtools::install_github("lachlandeer/hayashir")into the R console.
