ZrehenMeasure4All
Description
A generalized version of the Zrehen-measure which defines the neighbourhood with a Gabriel Graph and is therefore not restricted to grid-based projections.
Usage
ZrehenMeasure4All(Data, Projection, width, height, isToroid = FALSE,
isGrid = TRUE, plotGabriel = FALSE)
Arguments
Data |
[1:n,1:d] points in input room with d attributes |
Projection |
[1:n,1:2] projected points in output room, with index,x,y or index,line,column |
width |
Numeric: only necessary if toroid |
height |
Numeric: only necessary if toroid |
isToroid |
Boolean: are the points toroid? |
isGrid |
Boolean: is the grid a toroid? |
plotGabriel |
Boolean: plot the generated GabrielGraph (TRUE) or not (FALSE). Default: plotGabriel=FALSE. |
Value
List with
V$zrehen |
the raw zrehen measure |
V$normedzrehen |
the zrehen measure normed by the number of neighbours |
v$neighbourcounter |
the number of possible neighbours by which the zrehen measure is normed |
