Examples

r <- terra::rast(system.file("extdata/SICILY_1000m.tif", package="leastcostpath"))

x <- create_slope_cs(x = r, cost_function = "tobler", neighbours = 4)

locs <- sf::st_sf(geometry = sf::st_sfc(
sf::st_point(c(960745, 4166836)),
crs = terra::crs(r)))
locs <- sf::st_buffer(x = locs, dist = 25000)

y <- update_values(x = x, sf = locs, FUN = function(j) { j + 10})

output <- replace_values(x = x, y = y, sf = locs)

identical(y$conductanceMatrix, output$conductanceMatrix)
