plotclus {spatclus} | R Documentation |
Plots the data points and a representation of the cluster located.
plotclus(nomlst, m, limx = c(0, 100), limy = c(0, 100), col1 = 225, rcex = 0.68, pop, k=floor((m+1)/2))
nomlst |
A list corresponding to the "clus" function's return value. |
m |
The number of breaks of the model to be plotted. |
limx |
2 element vector containing the study area bounds of the X-axis. |
limy |
2 element vector containing the study area bounds of the Y-axis. |
col1 |
The color to be used for the cluster representation. |
rcex |
The size to be used for the disc surrounding the points localized in cluster. |
pop |
A 2 column matrix containing the underlying population coordinates. |
k |
The number of clusters to be displayed. |
A cluster groups together the points between two breaks with a low mean distance. The plotreg function allow to choose the number of clusters.
A R-graphic window containing the plot.
