The goal of contactdata is to provide access to social contact data for 152 countries. This data comes from
Kiesha Prem, Alex R. Cook, Mark Jit, Projecting social contact matrices in 152 countries using contact surveys and demographic data, PLoS Comp. Biol. (2017), https://doi.org/10.1371/journal.pcbi.1005697.
(please cite it in your publications, alongside this package).
contactdata offers an easier access to this data, makes it readily compatible with tidyverse packages, such as ggplot2, via the contact_countries() function, and provides an easy way to harmonise country nomenclature by using the countrycode package as authoritative name source.
You can install this package from CRAN:
or the development version from GitHub, via my r-universe:
The most basic function allows you to get matrix data for a specific country:
library(contactdata)
contact_matrix("France")

Because it is very likely that users of this package will also need data about the population in each age group, it is also bundled in this package for convenience. Please see ?age_df_countries for more information.
