Calculate n closest distances and durations by category

Creates sf of geometry type point for each source feature with the minimum distance and duration values to n nearest target features which match the applied category filter

create_time_distance_n_by_cat_sf(odm_object, filter_attribute, filter_value, n)

Arguments

odm_object	of type list encompassing a duration and a distance matrix, the source and target locations. Created by using either calc_odm or calc_odm_multicore
filter_attribute	A category column to subset the targets
filter_value	A string with a specific category value
n	An integer defining the number of minimum values to be incorporated

Value

sf object of geometry type point

See also

calc_odm() or calc_odm_multicore() for odm_object creation and create_time_distance_by_cat_sf to calculate only the nearest target location for a specific category

Examples

data(testdata)
od_result <- testdata$od_result
output_sf <- create_time_distance_n_by_cat_sf(
  odm_object = od_result,
  filter_attribute = "category", filter_value = "A", n = 3
