check_dup(bases, min_dist)

Arguments

current	starting projection, a list of basis of class "multi-bases"
index	index function
tries	the counter of the outer loop of the opotimiser
max.tries	the maximum number of iteration before giving up
...	other arguments being passed into the search_jellyfish()
bases	a list of bases extracted from the data collection object, see examples
min_dist	the minimum distance between two bases

Examples

library(dplyr)
res <- animate_xy(flea[, 1:6], guided_tour(lda_pp(cl = flea$species),
search_f = search_jellyfish))
bases <- res |> filter(loop == 1) |> pull(basis) |> check_dup(0.1)
animate_xy(data = flea[,1:6], tour_path = planned_tour(bases), col = flea$species)
