popdemo: Demographic Modelling Using Projection Matrices

Tools for modelling populations and demography using matrix projection models (MPMs). Designed to build on similar tools already available in 'popbio'. Specific foci are on indices of transient dynamics and use of control theory approaches, but 'popdemo' may also be useful for other implementations of MPMs, or matrix models in a more general sense.
