Social mixing matrices for infectious disease modelling in R

socialmixr is an R package to derive social mixing matrices from survey data.

Installation

The package can be installed using

install.packages("socialmixr")

The current development version can be installed using the remotes package

remotes::install_github("epiforecasts/socialmixr")

Usage

Contact matrices are computed through a small pipeline of composable functions: subsetting the survey, assigning age groups, optionally weighing participants, and computing the matrix. A minimal example using the included POLYMOD data:

library(socialmixr)
data(polymod)

polymod[country == "United Kingdom"] |>
  assign_age_groups(age_limits = c(0, 1, 5, 15)) |>
  compute_matrix()

Post-processing functions symmetrise(), split_matrix() and per_capita() can be piped after compute_matrix() to enforce symmetry, decompose the matrix, or convert to per-capita contact rates.
