Collecting all pairwise distances between input planes.

The distribution of all pairwise distances is useful to understand the optimisation in a guided tour, to compare e.g. different optimisation methods or different number of noise dimensions.

distanceDist(planes, nn = FALSE)

Arguments

planes	Input planes (e.g. result of guided tour)
nn	Set true to only consider nearest neighbour distances (dummy, not yet implemented)

Value

numeric vector containing all distances

Examples

planes1 <- purrr::rerun(10, tourr::basis_random(5))
planes2 <- purrr::rerun(10, tourr::basis_random(10))
d1 <- distanceDist(planes1)
d2 <- distanceDist(planes2)
d <- tibble::tibble(dist=c(d1, d2), dim=c(rep(5,length(d1)),rep(10,length(d2))))
ggplot2::ggplot(d) + ggplot2::geom_boxplot(ggplot2::aes(factor(dim), dist))
