plot.choicealpha: Plot to choose the mixing parameter

In ClustGeo: Hierarchical Clustering with Spatial Constraints

Description

Plot two curves of explained inertia (one for D0 and one for D1) calculated with choicealpha.

Usage

## S3 method for class 'choicealpha'
plot(
  x,
  norm = FALSE,
  lty = 1:2,
  pch = c(8, 16),
  type = c("b", "b"),
  col = 1:2,
  xlab = "alpha",
  ylab = NULL,
  legend = NULL,
  cex = 1,
  ...
)

Arguments

x	an object of class choicealpha.
norm	if TRUE, the normalized explained inertia are plotted. Otherwise, the explained inertia are plotted.
lty	a vector of size 2 with the line types of the two curves. See par
pch	a vector of size 2 specifying the symbol for the points of the two curves. See par
type	a vector of size 2 specifying the type of lines of the two curves. See par
col	a vector of size 2 specifying the colors the two curves. See par
xlab	the title fot the x axis.
ylab	the title fot the y axis.
legend	a vector of size two the the text for the legend of the two curves.
cex	text size in the legend.
...	further arguments passed to or from other methods.

Examples

data(estuary)
D0 <- dist(estuary$dat)
D1 <- as.dist(estuary$D.geo) # the geographic distances between the cities
range.alpha <- seq(0,1,0.1)
K <- 5
cr <- choicealpha(D0,D1,range.alpha,K,graph=FALSE)
