gretel
is a package for generalized path analysis. It implements new measures that
are described in a forthcoming research publication, as well as some traditional path
value measures described in Yang, Knoke (2001).
The exported functions in this package are
gpv
, which calculates Generalized Path Valueppv
, which calculates Probabilistic Path Valuebinary_distance
, peay_path_value
, flament_path_length
,
peay_average_path_value
, and flament_average_path_length
, which
calculate path value measures described in Yang, Knoke (2001).generate_proximities
, which generates a matrix of values representing the
measures of optimal paths from each source node (row index) to each target node
(column index).opt_gpv
, which identifies the path of optimal Generalized Path Value from
a particular source node to a particular target nodeopt_ppv
, which identifies the path of optimal Probabilistic Path Value from
a particular source node to a particular target nodeall_opt_gpv
, which identifies the 'gpv'-optimal paths from every source node
to every target nodeall_opt_ppv
, which identifies the 'ppv'-optimal paths from every source node
to every target nodeunpack
, which unpacks the Dijkstra-format encoded shortest paths returned by
all_opt_gpv
and all_opt_ppv
. See their help pages for details.The package also includes three example datasets
