two_circle_density_dat: Point cloud of two circles of same size but different point density

Description

A dataset containing 500 randomly generated points: 100 points from low point density circle and 400 from high point density circle.

Usage

data(two_circle_density_dat)

Format

A matrix of 500 rows and 2 columns

Examples

# NOT RUN {
# load data
data(two_circle_density_dat)

# input variables
Xlim <- c(-3,6)
Ylim <- c(-3,3)
lim <- cbind(Xlim, Ylim)
by <- 0.1
spseq <- seq(0.01,1,length.out=20)

# compute persistence terrace
two_circle_density_pt <- computept(two_circle_density_dat,sp=spseq,lim=lim,by=by)

# }
# NOT RUN {
# compute persistence terrace with parallel option
two_circle_density_pt <- computept(two_circle_density_dat,sp=spseq,lim=lim,by=by,par=TRUE)
# }
# NOT RUN {
# draw persistence terrace, satellite view
