%description
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.
