Implements functions for working with absorbing Markov chains. The
implementation is based on the framework described in "Toward a unified
framework for connectivity that disentangles movement and mortality in space
and time" by Fletcher et al. (2019) <doi:10.1111/ele.13333>, which applies
them to spatial ecology. This framework incorporates both resistance and
absorption with spatial absorbing Markov chains (SAMC) to provide several
short-term and long-term predictions for metrics related to connectivity in
landscapes. Despite the ecological context of the framework, this package
can be used in any application of absorbing Markov chains.
