The image function visualizes the joint distribution of two preferences (if 'all.pref=FALSE') given 'xpref' and 'ypref', as well as the marginal distribution of all preferences (if 'all.pref=TRUE'). The joint distribution can be shown as proportions (if 'proportion=TRUE') or raw vote counts (if 'proportion=FALSE').
