  closedistances = NULL,
  U,
  sicks,
  new.sicks = NULL,
  delta = 0.005,
  dist_areas = dist_areas_f(U, delta)
)

Arguments

closedistances	NULL, or a named list with 2 named elements: closedistances$ra, closedistances$id
U	a data.frame with the variables hexagon (can be any bin identifier), x, y : coordinates,
sicks	a vector of integers indicating the row numbers in U for sicks
new.sicks	a vector of integers indicating the row numbers in U for new sicks
delta	a positive number : a threshold
dist_areas:	a function between

Value

NULL, or a named list with 2 named elements: closedistances$ra, closedistances$id

Examples

data(UE,package="Strategy")
delta<-.005
sicks<-which(UE$I001=="sick")
