The goal of cepiigravity is to provide the same data from Gravity ready to be used in R (i.e. with the gravity package).
The package provides data on countries and distance measures alongside dummy variables indicating whether two countries are contiguous, share a common language or a colonial relationship, and others.
cepiigravity can be installed by running
# install.packages("remotes")
install_github("pachamaltese/cepiigravity")
The main source to obtain the data in this package is:
Conte, M., Cotterlaz, P. & Mayer, T. (2021). The CEPII Gravity Database. CEPII Working Paper 2022-05.
