 [socialmixr](https://github.com/epiforecasts/socialmixr) is an `R` package to derive social mixing matrices from survey data. These are particularly useful for age-structured [infectious disease models](https://en.wikipedia.org/wiki/Mathematical_modelling_of_infectious_disease). For background on age-specific mixing matrices and what data inform them, see, for example, the paper on POLYMOD by [@mossong_social_2008].

 The contact matrices can also be plotted with the `matrix_plot()` function as a grid of colored rectangles with the numeric values in the cells. Heat colors are used by default, though this can be changed.
