Visualize point matching.

Source: R/visualizePointMatching.R

Visualize a point matchings. Points and lines between the matched points are drawn in order to visualize the assignment.

visualizePointMatching(x, y, point.matching, highlight.longest = 0L)

Arguments

x

[Network | matrix]
Network or (n x 2) matrix.
y

[Network | matrix]
Network or (n x 2) matrix.
point.matching

[matrix]
Point matching received via getOptimalPointMatching for example.
highlight.longest

[integer(1)]
Number of longest distances which should be particularly highlighted. Default is 0.

Value

[ggplot]

Examples

# point matching on networks
x = generateRandomNetwork(n.points = 20L, upper = 100)
y = generateClusteredNetwork(n.points = 20L, n.cluster = 2L, upper = 100)
if (FALSE) {
pm = getOptimalPointMatching(x$coordinates, y$coordinates)
print(visualizePointMatching(x, y, pm, highlight.longest = 2L))
}

# point matching on point clouds
x = matrix(runif(20L), 2L)
y = matrix(runif(20L), 2L)
if (FALSE) {
pm = getOptimalPointMatching(x, y)
print(visualizePointMatching(x, y, pm))
