Description
Move branching nodes to areas with higher point density
Usage

ShiftBranching(X, TargetPG, SelectionMode = "NodePoints",
DensityRadius = NA, MaxShift = 3, Compensate = FALSE, BrIds = NULL,
TrimmingRadius = Inf)
Arguments
X
numeric matrix, the data matrix
TargetPG
list, the ElPiGraph structure to extend
SelectionMode
string, the mode to use to shift the branching points. The "NodePoints" and "NodeDensity" modes are currently supported
DensityRadius
positive numeric, the radius to be used when computing point density if SelectionMode = "NodeDensity"
MaxShift
positive integer, the maxium distance (as number of edges) to consider when exploring the branching point neighborhood
Compensate
booelan, should new points be included to compensate for olter one being removed (currently not implemented)
BrIds
integer vector, the id of the branching points to consider. Id not associted with node possessing degree > 2 will be ignored
TrimmingRadius
positive numeric, the trimming radius used to control distance
Value
a list with two components: NodePositions (Containing the new nodes positions) and Edges (containing the new edges)
The function explore the neighborhood of branching point for nodes with higher point density. It such point is found, to graph will be
modified so that the new found node will be the new branching point of the neighborhood.
