plotDensityClust | R Documentation |
Generate a single panel of up to three diagnostic plots for a
densityClust
object.
plotDensityClust(x, type = "all", n = 20, mds = NULL, dim.x = 1, dim.y = 2, col = NULL, alpha = 0.8)
x |
A densityCluster object as produced by |
type |
A character vector designating which figures to produce. Valid
options include |
n |
Number of observations to plot in the gamma graph. |
mds |
A matrix of scores for observations from a Principal Components Analysis or MDS. If omitted, and a MDS plot has been requested, one will be calculated. |
dim.x, dim.y |
The numbers of the dimensions to plot on the x and y axes of the MDS plot. |
col |
Vector of colors for clusters. |
alpha |
Value in |
A panel of the figures specified in type
are produced.
If designated, clusters are color-coded and labelled. If present in
x
, the rho and delta thresholds are designated in the
decision graph by a set of solid black lines.
