ClustGeo (version 2.1)

plot.choicealpha: Plot to choose the mixing parameter

Description

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

Usage

# S3 method for 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.
