breakThrough: Says if there is a connected path between the boundary limits

In mathphysmx/percolation: Continuum percolation of Poisson sticks

Description

Says if there is a connected path between the boundary limits along a given direction. Two posible directions:vertical or horizontal. Not both.

Usage

breakThrough(bi, lims, clust)

Arguments

bi	List with 2 integer vectors wm and wM. ID of line segments touching the study interval boundary. The result from touchBoundary.
lims	Numeric 2-dimensinal vector with the limits of the study interval.
clust	a result from graph.adjacency.

Value

A logical vector of length equals to the number of clusters. Each component answering the question: There is a connected path from lims[1] to lims[2]?

Examples

n <- 6; xl <- -0.3; xr <- 1.2
set.seed(123) #9
endpts <- data.frame(x0 = runif(n, xl, xr),
y0 = runif(n, xl, xr),
x1 = runif(n, xl, xr),
y1 = runif(n, xl, xr))
plotSegments(segment = endpts)
lims <- c(0,1)
abline(h=lims, v= lims, col = 'lightgray')
te <- touchBoundary(w0 = endpts$x0, w1 = endpts$x1, lims = lims)
library(igraph)
eAdjClust <- clusters(graph.adjacency(incidence.matrix(endpts)))
breakThrough(bi=te, lims=0:1, clust = eAdjClust)
