A class that holds density information computed from point data along a river network.
Created by makeriverdensity from point data and a river network. Contains all information for plotting in plot.riverdensity.
densities
:Object of class "list"
. Each list element corresponds to a unique value of survey. Each element is itself of class "list"
, with each element corresponding to a segment from the associated river network. Each element is a vector of class "numeric"
, with values equal to the scaled densities calculated at the river network vertices stored in $densverts
of the associated river network segment.
endptverts
:List of vectors of class "numeric"
. Each list element is a vector of the vertices of the endpoints of the subsegments considered for density calculation. Each list element corresponds to a river segment from the associated river network.
densverts
:List of vectors of class "numeric"
. Each element is a vector of the vertices of the points of the subsegments considered for density calculation, that were used for density calculation. Each list element corresponds to a river segment from the associated river network.
pointsegs
:Vector of class "numeric"
. Defined as the segment numbers of the point data used for density calculation.
pointverts
:Vector of class "numeric"
. Defined as the vertex numbers of the point data used for density calculation.
survey
:Vector of class "numeric"
or class "character"
. Defined as the survey identifiers associated with the point data used for density calculation.
rivers
:Object of class "rivernetwork"
