plotpt: Draws a persistence terrace.

In pterrace: Persistence Terrace for Topological Data Analysis

Description

Draws a persistence terrace.

Usage

plotpt(xyz, dimension, cmax = 10, satellite = T)

Arguments

xyz	a list of computed persistence terraces returned by the function computept.
dimension	an integer selecting the dimension of the persistence terrace to plot.
cmax	an integer specifying the maximum number of colors to be used. The default value is 10.
satellite	a logical variable to select a viewpoint. If FALSE, plots the overall view of the persistence terrace. The default value is TRUE.

Value

The function plotpt returns the persistence terrace graphic.

Examples

# load three circle data
data(three_circle_dat)

# input variables
Xlim <- c(-4,12)
Ylim <- c(-4,9)
lim <- cbind(Xlim, Ylim)
by <- 0.1
spseq <- seq(0.01,1.5,length.out = 25)

# compute persistence terrace
## Not run: 
threecirclept <- computept(three_circle_dat,sp=spseq,lim=lim,by=by)

# draw persistence terrace, satellite view
plotpt(threecirclept,dimension=1)
# draw persistence terrace, overall view
plotpt(threecirclept,dimension=1,satellite=FALSE)

## End(Not run)
