plotCSregsInt: The plot of the Central Similarity (CS) Proximity Regions for a general interval (vertices jittered along y-coordinate) - one interval case

Description

Plots the points in and outside of the interval int and also the CS proximity regions (which are also intervals).

CS proximity regions are constructed with expansion parameter $t>0$ and centrality parameter c in $(0,1)$. For better visualization, a uniform jitter from $U(-Jit,Jit)$ (default for $Jit=.1$ times range of proximity regions and dat) is added to the y-direction.

centers is a logical argument, if TRUE, plot includes the centers of the intervals as vertical lines in the plot, else centers of the intervals are not plotted.

Usage

plotCSregsInt(
  dat,
  t,
  c = 0.5,
  int,
  Jit = 0.1,
  main = "",
  xlab = "",
  ylab = "",
  xlim = NULL,
  ylim = NULL,
  centers = FALSE,
  ...
)

Arguments

dat

A set of 1D points for which CS proximity regions are to be constructed.

t

A positive real number which serves as the expansion parameter in CS proximity region.

c

A positive real number in $(0,1)$ parameterizing the center inside $int=(a,b)$. For the interval, $int=(a,b)$, the parameterized center is $M_c=a+c(b-a)$; default=0.5.

int

A vector of two real numbers representing an interval.

Jit

A positive real number that determines the amount of jitter along the y-axis, default is 0.1 and dat points are jittered according to $U(-Jit,Jit)$ distribution along the y-axis where Jit equals to the range of dat and proximity region intervals multiplied by Jit).

main

Title of the main heading of the plot.

xlab, ylab

Titles for the x and y axes, respectively (default="" for both).

xlim, ylim

Numeric vectors of length 2, giving the x- and y-coordinate ranges.

centers

A logical argument, if TRUE, plot includes the centers of the intervals. as vertical lines in the plot, else centers of the intervals are not plotted.

…

Additional plot parameters.

Value

Plot of the CS proximity regions for 1D points in or outside the interval int
