Social Mixing Matrices for Infectious Disease Modelling.
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.
